What is the solution set for \(x\) in the inequality \(\frac{5x}{6}+1>\frac{x}{3}+9\)?

Answer and explanation

Correct answer: \(x>16\)

The least common denominator is 6. Multiplying both sides by the positive number 6 does not change the inequality sign: \(5x+6>2x+54\). Thus, \(3x>48\), so \(x>16\). Therefore, option A is correct. The distractor \(x\geq16\) is incorrect because substituting \(x=16\) makes both sides equal, whereas the inequality is strict. Exam tip: when an inequality is multiplied or divided by a negative number, its sign must be reversed.
