What is the solution of the inequality \(3(x+2)\le 2x+11\)?

Answer and explanation

Correct answer: \(x\le 5\)

Expanding the bracket gives \(3x+6\le 2x+11\). Subtracting \(2x\) from both sides yields \(x+6\le 11\), so \(x\le 5\). Option B reverses the inequality incorrectly; the sign does not change because we have not multiplied or divided by a negative number. Exam tip: expand brackets first and collect variable terms on one side.
