How can two different equations have the same solution??

1. How can two different equations have the same solution?? x+7= 25 has the same solution as the  equation x + 14 = 32

2. In this lesson you will learn that properties of equality apply to equations containing unknown valuesby making connections to real numbers

3. 9 = 9 9 – 6 = 9– 6 3 = 3

4. 5 = 5 5 + 7 = 5 + 7 12 = 12

5. What does “solution” mean in math? x-2=0 2 is a solution

6. Forgetting properties of equality apply to algebraic expressions

7. x+5 = 10 and x+15 = 20 x+5 + 10= 10 + 10 x+15 = 20

8. x + 7 = 14 and x – 2 = 5 x + 7 - 9= 14- 9 x – 2 = 5

9. In this lesson you have learned how to tell if equations have the same solutionby using the principles of equality

10. Do the pairs of algebraic expressions have the same solution? x = 7 and x + 8 = 15 x + 4 = 6 and x + 2 = 8

11. How would you know that two expressions do not have the same solution? Show your work and provide an example

12. Using the mathematical definition of solution, what is the solution for x + 2 = 5? Is it the same solution as x + 6 = 9? Show your work.

13. Describe the steps you would take to determine if X + 7 =14 and x -3= 4 have the same solution. Complete the problem and show yourwork.

14. Do x + 7 = 4 and x + 10 = 7 have the same solution? Do x + 9 = 20 and x + 1 = 12 have the same solution?
