Step-by-step explanation:

Step 1: Define

Identify

4(1) + 12(x + 3) - 6(x - 5) = 4(12) + 4(x)

Step 2: Solve for x

  1. Simplify:                                                                                                             4 + 12(x + 3) - 6(x - 5) = 48 + 4x
  2. [Distributive Property] Distribute parenthesis:                                               4 + 12x + 36 - 6x + 30 = 48 + 4x
  3. Combine like terms:                                                                                         6x + 70 = 48 + 4x
  4. [Subtraction Property of Equality] Subtract 4x on both sides:                      2x + 70 = 48
  5. [Subtraction Property of Equality] Subtract 70 on both sides:                      2x = -22
  6. [Division Property of Equality] Divide 2 on both sides:                                  x = -11
