Which equation has solution x = -3?

A)
2x - 7 = -1

B)
3x + 8 = 1

C)
1
2
x + 8 = 10

D)
1
2
(2x - 6) = -6

Substitute x=-3 into each of the given equations, until you find the equation that is true after this substitution.

Case 1: 2x - 7 = -1; letting x = -3, we get 2(-3) - 7 = -1. Is this true? NO.

Case 2: Move on to the next equation and subst. x = -3 in the same manner. Is the equation true?

and so on.
