Step-by-step explanation:

Step 1: Define equation

-2(x - 4) = -16

Step 2: Solve for x

  1. Distribute -2:                    -2x + 8 = -16
  2. Isolate x term:                  -2x = -24
  3. Isolate x:                           x = 12

Step 3: Check

Plug in x to verify it's a solution.

  1. Substitute:                    -2(12 - 4) = -16
  2. Subtract:                       -2(8) = -16
  3. Multiply:                        -16 = -16

Here we see that -16 does indeed equal -16.

∴ x = 12 is a solution of the equation.
