What will be the solution set of (\frac{2x+1}{3}\le \frac{x-4}{2})?

Answer and explanation

Correct answer: \(x\le -14\)

Multiplying both sides by the positive number 6 does not change the inequality sign: \(2(2x+1)\le 3(x-4)\), so \(4x+2\le 3x-12\). Subtracting \(3x\) and 2 from both sides gives \(x\le -14\). Hence, option A is correct. The closest distractor, \(x<-14\), excludes \(x=-14\), although this value satisfies the inequality. Exam tip: Reverse an inequality sign only when multiplying or dividing by a negative number.
