Practice and Homework Lesson 2-3 Answer Key
In this lesson, we will be discussing the answers to the practice and homework problems from Lesson 2-3. These problems focused on solving equations with one variable using addition and subtraction.
To solve these equations, we used the properties of equality and inverse operations. We started by isolating the variable by applying inverse operations to both sides of the equation. We then simplified both sides and determined the value of the variable that makes the equation true.
Let’s take a look at some of the answers to the practice problems:
- Problem 1: 3x – 5 = 16
- Solution: We want to isolate the variable on one side, so we add 5 to both sides to get 3x = 21. Then, we divide both sides by 3 to get x = 7.
- Problem 2: 2y + 7 = 15
- Solution: To isolate the variable, we subtract 7 from both sides to get 2y = 8. Then, we divide both sides by 2 to get y = 4.
- Problem 3: -4z + 9 = -5
- Solution: Here, we need to isolate the variable on one side. We subtract 9 from both sides to get -4z = -14. Then, we divide both sides by -4 to get z = 3.5.
These are just a few examples of the types of problems we worked on in this lesson. By practicing these equations and using inverse operations, you will become proficient in solving equations with one variable.

Step-by-step Solutions to Practice and Homework Lesson 2-3 Problems
In this lesson, we will go through the step-by-step solutions to the problems found in practice and homework lesson 2-3. These problems are designed to help you practice and reinforce the concepts learned in the lesson.
Problem 1: Solve the equation 3x + 5 = 17.
To solve this equation, we want to isolate the variable x on one side of the equation. We can do this by subtracting 5 from both sides of the equation: 3x + 5 – 5 = 17 – 5. This simplifies to 3x = 12. Next, we divide both sides of the equation by 3 to solve for x: 3x/3 = 12/3. This gives us x = 4.
Problem 2: Find the missing angle in the triangle below.
We can use the fact that the angles in a triangle add up to 180 degrees to solve this problem. Let’s denote the missing angle as x. We know that the sum of the angles in the triangle is 180 degrees, so we can write the equation: 60 + 80 + x = 180. Simplifying the equation, we have x = 180 – 60 – 80. This gives us x = 40.
Problem 3: Solve the inequality 2x + 3 < 11.
To solve this inequality, we want to isolate the variable x on one side of the inequality. We can do this by subtracting 3 from both sides of the inequality: 2x + 3 – 3 < 11 - 3. This simplifies to 2x < 8. Next, we divide both sides of the inequality by 2 to solve for x: 2x/2 < 8/2. This gives us x < 4. Therefore, the solution to the inequality is x < 4.
These are just a few examples of the step-by-step solutions to the problems found in the practice and homework lesson 2-3. Remember to carefully follow each step to find the correct solution. Keep practicing and you will continue to improve your problem-solving skills!
