Understanding the Problem
In this section, we will delve into the process of understanding and breaking down a mathematical equation. By dissecting the equation -6 + 2p + 3 < 7, we will identify its different components and discuss the purpose of the inequality symbol (<).
Breaking down the equation: -6 + 2p + 3 < 7
To begin, let’s analyze the equation -6 + 2p + 3 < 7. This equation contains several elements that we need to understand in order to solve it accurately. Each component plays a crucial role in determining the solution.
Identifying the different components of the equation
The equation consists of three terms: -6, 2p, and 3. The term -6 represents a constant value, while 2p is a variable term involving the unknown variable, p. Lastly, the term 3 is another constant value.
Discussing the purpose of the inequality symbol (<)
The inequality symbol (<) in the equation signifies a comparison between two expressions. In this case, it indicates that the sum of -6, 2p, and 3 is less than 7. The goal is to find the value(s) of p that satisfy this inequality.
Understanding the problem is crucial because it allows us to grasp the context and meaning behind the equation. By breaking down the equation and identifying its components, we can proceed to simplify and solve it accurately.
Now that we have a clear understanding of the problem, let’s move on to the next section: III. Simplifying the Equation.
Simplifying the Equation
Simplifying mathematical equations is a crucial step in solving problems and finding solutions. By breaking down complex equations into simpler forms, we can easily understand and manipulate them to find the desired outcome. In this section, we will discuss the step-by-step process of simplifying equations and demonstrate how to perform each step accurately.
Step-by-step process of simplifying the equation
To simplify an equation, we need to follow a systematic approach that involves combining like terms and isolating the variable. Let’s take the equation -6 + 2p + 3 < 7 as an example and simplify it using the following steps:
Combining like terms: In this equation, the terms -6 and 3 are constants, while 2p represents the variable. To simplify, we can combine the constant terms by adding -6 and 3, which gives us -3. The equation now becomes 2p – 3 < 7.
Isolating the variable (p): Our goal is to isolate the variable on one side of the equation. To do this, we need to eliminate the constant term (-3) from the left side. We can achieve this by adding 3 to both sides of the equation. This results in 2p < 10.
Dividing by the coefficient of the variable: To fully isolate the variable, we need to divide both sides of the equation by the coefficient (2) of the variable (p). Dividing both sides by 2 gives us p < 5.
Demonstrating how to perform each step accurately
Let’s demonstrate the steps mentioned above using the equation -6 + 2p + 3 < 7:
Combining like terms: We add -6 and 3 to get -3. The equation becomes 2p – 3 < 7.
Isolating the variable (p): We add 3 to both sides of the equation. This gives us 2p < 10.
Dividing by the coefficient of the variable: We divide both sides of the equation by 2. This yields p < 5.
By following these steps, we have successfully simplified the equation and isolated the variable (p). The final simplified equation, p < 5, represents the solution to the original inequality.
Simplifying equations is essential as it allows us to focus on the variable and understand its relationship with other components in the equation. It provides a clear path towards finding the solution and helps avoid confusion or errors during the problem-solving process.
Remember, accuracy is crucial when simplifying equations. Any mistakes made during the simplification process can lead to incorrect solutions. Therefore, it is important to double-check each step and ensure the equation is correctly simplified before moving forward.

Solving the Inequality
Solving inequalities is an essential skill in mathematics. It allows us to find the range of values that satisfy a particular equation. In this section, we will delve into the concept of inequality solutions and demonstrate how to apply the simplified equation to find the solution.
Explaining the concept of inequality solutions
An inequality solution refers to the set of values that make an inequality statement true. Unlike equations, which have a specific solution, inequalities often have multiple solutions. These solutions can be represented on a number line or in interval notation.
Applying the simplified equation to find the solution
Once we have simplified the inequality equation, we can proceed to find the solution. Let’s consider the example equation: -6 + 2p + 3 < 7.
To solve this inequality, we follow a step-by-step process:
Combining like terms: In this example, we combine -6 and 3 to get -3. The equation now becomes 2p – 3 < 7.
Isolating the variable (p): To isolate the variable, we need to get rid of any constants or coefficients attached to it. In this case, we add 3 to both sides of the equation, resulting in 2p < 10.
Now that we have simplified the equation, we can proceed to find the solution.
To isolate the variable p, we divide both sides of the equation by 2. This gives us p < 5 as the solution.
Discussing the different possible outcomes and solutions
Inequality solutions can have different forms depending on the inequality symbol used. In our example, the inequality symbol is “<,” which represents “less than.” This means that any value less than 5 will satisfy the inequality.
However, it’s important to note that the solution is not inclusive of 5 itself. This is because the inequality symbol “<” indicates that the value of p can be any number less than 5, but not equal to 5.
To represent the solution on a number line, we would use an open circle at 5 and shade the region to the left of it. In interval notation, the solution would be represented as (-∞, 5).
Verifying the Solution
To ensure the accuracy of our solution, we can substitute the value of p back into the original inequality equation and check if it holds true.
Let’s substitute p = 4 into the original equation: -6 + 2(4) + 3 < 7.
Simplifying this equation, we get -6 + 8 + 3 < 7, which becomes 5 < 7. Since this statement is true, we can confirm that p = 4 is indeed a valid solution.
Real-World Applications
Understanding and solving inequalities have practical applications in various real-world scenarios. For example, it can be used to determine the range of temperatures at which a chemical reaction occurs, or to analyze the profit margins of a business.
By solving inequalities, we can make informed decisions based on the constraints and limitations presented by the problem at hand. It allows us to identify the possible outcomes and make appropriate adjustments to achieve desired results.
Solving inequalities is a fundamental skill that allows us to find the range of values that satisfy a given equation. By following a systematic approach, we can simplify the equation and find the solution. It is crucial to understand the concept of inequality solutions and verify our solutions to ensure accuracy.
As we encounter more complex equations and real-world problems, practicing the skill of solving inequalities becomes increasingly important. So, let’s continue to enhance our mathematical abilities by tackling similar equations and expanding our problem-solving skills.
Verifying the Solution
After solving a mathematical equation or inequality, it is crucial to verify the solution to ensure its accuracy. Verifying the solution involves substituting the obtained value back into the original equation and confirming if both sides of the equation are equal. This step is essential in order to validate the solution and avoid any potential errors.
Substituting the solution back into the original equation
To verify the solution, we substitute the value we obtained for the variable back into the original equation. By doing so, we can check if the equation holds true for the given value. Let’s consider the example equation: -6 + 2p + 3 < 7, where we found that p = 5.
Substituting p = 5 into the equation, we have:
-6 + 2(5) + 3 < 7
Demonstrating how to confirm if the solution is correct
Now, let’s simplify the equation further:
-6 + 10 + 3 < 7
Combining like terms, we get:
7 < 7
Here, we can see that the left side of the equation is not less than the right side. In fact, both sides are equal. This means that the solution we obtained, p = 5, is not valid for this equation. Therefore, we need to re-evaluate our steps and find the correct solution.
It is important to note that if the equation had been a strict inequality, such as < instead of <=, the solution p = 5 would not have been valid. In strict inequalities, the solution does not include the value that makes the equation equal. However, in this case, since the equation is not strict, the solution p = 5 is still a possibility.
Importance of verifying the solution
Verifying the solution is a critical step in the problem-solving process. It helps us identify any errors made during the simplification or solving stages. By substituting the obtained value back into the original equation, we can ensure that the equation holds true for that particular value. If the equation does not hold true, it indicates that our solution is incorrect, and we need to revisit our steps to find the correct solution.
Verifying the solution also helps build confidence in our problem-solving skills. It allows us to double-check our work and avoid any careless mistakes. Additionally, it reinforces the understanding of the mathematical concepts involved in solving equations and inequalities.
Verifying the solution is an essential step in solving mathematical equations and inequalities. It ensures the accuracy of the obtained solution and helps identify any errors made during the solving process. By substituting the solution back into the original equation, we can confirm if the equation holds true. If it does, we can be confident in the validity of our solution. However, if the equation does not hold true, we need to re-evaluate our steps and find the correct solution.
It is crucial to emphasize the importance of verifying the solution to enhance problem-solving skills. By practicing this step regularly, we can develop a thorough understanding of mathematical equations and inequalities.
