Step-by-step explanation:

Step 1: Define

8 - 3(1 - m) = -7

Step 2: Solve for m

[Subtraction Property of Equality] Subtract 8 on both sides:                       -3(1 - m) = -15[Division Property of Equality] Divide -3 on both sides:                               1 - m = 5[Subtraction Property of Equality] Subtract 1 on both sides:                         -m = 4[Division Property of Equality] Divide -1 on both sides:                               m = -4
