Question

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.

Answer 1

X=-4                       x=0                x=5
5-4-12=-4-7          5+0-12=0-7   5+5-12=5-7
-11=-11                 -7=-7              -2=-2
