What is the solution of the inequality \(\frac{x}{2}-\frac{x}{3}>1\)?

Answer and explanation

Correct answer: \(x>6\)

\(\frac{x}{2}-\frac{x}{3}=\frac{3x-2x}{6}=\frac{x}{6}\), so \(\frac{x}{6}>1\). Multiplying both sides by the positive number 6 gives \(x>6\). Option C is incorrect because the original sign is \(>\), not \(\geq\); therefore, 6 itself is not included in the solution set. Exam tip: reverse the inequality sign only when multiplying or dividing by a negative number; here, 6 is positive.
