What is the solution of the inequality (3x − 2)/2 ≥ 5?

Answer and explanation

Correct answer: x ≥ 4

The governing concept is solving a fractional linear inequality by multiplying by a positive denominator. From (3x − 2)/2 ≥ 5, multiply both sides by 2. Since 2 is positive, the inequality sign remains ≥, producing 3x − 2 ≥ 10. Add 2 to both sides to obtain 3x ≥ 12, and divide by positive 3 to get x ≥ 4. Equality must be retained because the original symbol includes equality. Checking the boundary, x = 4 gives (12 − 2)/2 = 5, so it satisfies the inequality exactly. Values larger than 4 also work, while values smaller than 4 do not. Option B reverses the direction, option C incorrectly excludes x = 4, and option D gives both the wrong direction and endpoint. Hence option A is correct.
