Explanation:

Step 1: Define

-(8x + 3) = -23 - 3x

Step 2: Solve for x

  1. Factor GCF: -(8x + 3) = -(23 + 3x)
  2. [Division Property of Equality] Divide -1 on both sides: 8x + 3 = 23 + 3x
  3. [Subtraction Property of Equality] Subtract 3x on both sides: 5x + 3 = 23
  4. [Subtraction Property of Equality] Subtract 3 on both sides: 5x = 20
  5. [Division Property of Equality] Divide 5 on both sides: x = 4
