Step-by-step explanation:

Step 1: Define

Identify

6 = -2x - 6

Step 2: Solve for x

1. [Addition Property of Equality] Add 6 on both sides:                                    12 = -2x
2. [Division Property of Equality] Divide -2 on both sides:                                -6 = x
3. Rewrite:                                                                                                             x = -6
