Step-by-step explanation:

Step 1: Define

2(3x + 4) - 3(x - 1) = x - 1

Step 2: Solve for x

  1. [Distributive Property] Distribute:                                                                    6x + 8 - 3x + 3 = x - 1
  2. Combine like terms:                                                                                         3x + 11 = x - 1
  3. [Subtraction Property of Equality] Subtract x on both sides:                         2x + 11 = -1
  4. [Subtraction Property of Equality] Subtract 11 on both sides:                        2x = -12
  5. [Division Property of Equality] Divide 2 on both sides:                                  x = -6
