What is the solution of (2-\frac{3x-1}{4}\ge \frac{x+5}{2})?

Answer and explanation

Correct answer: \(x\le -\frac{1}{5}\)

Multiplying both sides of the inequality by the positive number 4 gives \(8-(3x-1)\ge 2(x+5)\). Thus, \(9-3x\ge 2x+10\), so \(-1\ge 5x\). Dividing by 5 gives \(x\le -\frac{1}{5}\). Option B excludes \(-\frac{1}{5}\), but the original inequality contains \(\ge\). Exam tip: the inequality sign does not reverse when multiplying or dividing by a positive number.
