What is the solution of the inequality \(\frac{2x+1}{3}\leq\frac{x+9}{6}\)?

Answer and explanation

Correct answer: \(x\leq\frac{7}{3}\)

The least common multiple of the denominators 3 and 6 is 6. Multiplying by 6 does not reverse the inequality because 6 is positive: \(2(2x+1)\leq x+9\), so \(4x+2\leq x+9\). Thus, \(3x\leq7\), giving \(x\leq\frac{7}{3}\). Therefore, option A is correct. Option C is incorrect because it excludes \(x=\frac{7}{3}\), even though equality is allowed in the original inequality. Exam tip: reverse the inequality sign only when multiplying or dividing by a negative number; here, 6 is positive.
