Questions & Step-by-Step Solutions

Find the solution set for the inequality 2(x - 1) ≥ 4.
Correct Answer: x ≥ 3
  • Step 1: Start with the inequality: 2(x - 1) ≥ 4.
  • Step 2: Distribute the 2 on the left side: 2 * x - 2 * 1 ≥ 4, which simplifies to 2x - 2 ≥ 4.
  • Step 3: Add 2 to both sides of the inequality to isolate the term with x: 2x - 2 + 2 ≥ 4 + 2, which simplifies to 2x ≥ 6.
  • Step 4: Divide both sides by 2 to solve for x: 2x / 2 ≥ 6 / 2, which simplifies to x ≥ 3.
