Explanation:

Step 1: Define

Identify.

-3(x + 2) = 16 - x

Step 2: Solve for x

1. [Distributive Property] Distribute -3: -3x - 6 = 16 - x
2. [Addition Property of Equality] Add x on both sides: -2x - 6 = 16
3. [Addition Property of Equality] Add 6 on both sides: -2x = 22
4. [Division Property of Equality] Divide -2 on both sides: x = -11
