Step-by-step explanation:

Step 1: Define

Identify

2(x - 3) = (x - 1) + 7

Step 2: Solve for x

  1. Combine like terms [Addition]:                                                                        2(x - 3) = x + 6
  2. [Distributive Property] Distribute 2:                                                                 2x - 6 = x + 6
  3. [Addition Property of Equality] Add 6 on both sides:                                    2x = x + 12
  4. [Subtraction Property of Equality] Subtract x on both sides:                         x = 12
