Step-by-step 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
