Step-by-step explanation:

Step 1: Define

Identify.

3x + 2 = x + 4(x + 2)

Step 2: Solve for x

  1. [Subtraction Property of Equality] Subtract x on both sides:                        2x + 2 = 4(x + 2)
  2. [Distributive Property] Distribute 4:                                                               2x + 2 = 4x + 8
  3. [Subtraction Property of Equality] Subtract 4x on both sides:                      -2x + 2 = 8
  4. [Subtraction Property of Equality] Subtract 2 on both sides:                        -2x = 6
  5. [Division Property of Equality] Divide -2 on both sides:                                x = -3

Answer:

x=-3

Step-by-step explanation:

3x+2=x+4(x+2)

3x+2=x+4x+8

3x=5x+6

3x-6=5x

-6=2x

x=-3
