Given the equation 5 + x - 12 = x - 7.

Part A. Solve the equation 5 + x - 12 = x - 7. In your final answer, be sure to state the solution and include all of your work.

Part B. Use the values x = -4, 0, 5 to prove your solution to the equation 5 + x - 12 = x - 7. In your final answer, include all of your calculations

Part A:

First we do 5 + x - 12 = x - 7, to  x - 12= x - 7 - 5, which gives us x = x.

Part B:

1. 5 - 4 - 12 = - 4 -7 | -11 = -11
2. 5 + 0 - 12 = 0 - 7 | -7 = -7
3. 5 + 4 - 12 = 5 - 7 | -2 = -2

Hope this helped! c:
