Step-by-step explanation:

Step 1: Define

g(x) = 2(x - 4)

g(x) = 20

Step 2: Solve for x

  1. Substitute:                               20 = 2(x - 4)
  2. Divide 2 on both sides:          10 = x - 4
  3. Add 4 to both sides:               14 = x
  4. Rewrite:                                    x = 14
