Choose the solution of (\frac{2x-5}{3}+\frac{x+1}{6}\le 4).

Answer and explanation

Correct answer: \(x\le \frac{33}{5}\)

The LCM of the denominators is 6. Multiplying the inequality by 6 gives \(2(2x-5)+(x+1)\le 24\). Thus, \(5x-9\le 24\), so \(5x\le 33\) and \(x\le \frac{33}{5}\). Option C wrongly excludes equality, although the original inequality contains \(\le\). Exam tip: multiplying an inequality by a positive number does not reverse its sign.
