Question

For which equation would x = 12 be a solution?

12 ÷ x > 12
12 - x ≥ 4
12x < 200

Answer 1

12x < 200

Explanation:

Substitute x = 12 into the left side of the inequality and compare with right side, that is

12 ÷ 12 = 1 < 12 ← not a solution

12 - 12 = 0 < 4 ← not a solution

12 × 12 = 144 < 200 ← this is a solution
