Step 1: Define

Identify

2(4 + 2x) ≥ 5x + 5

Step 2: Solve for x

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