What is the solution set of (2-\frac{5x-1}{4}<\frac{x+7}{2})?

Answer and explanation

Correct answer: \(x>-\frac{5}{7}\)

Multiplying both sides by the positive number 4 does not change the inequality sign: \(8-(5x-1)<2x+14\). Thus, \(9-5x<2x+14\), which gives \(-7x<5\). Dividing by \(-7\) reverses the inequality, so \(x>-\frac{5}{7}\). Option C incorrectly includes equality, whereas the original inequality is strict. Exam tip: always reverse an inequality sign when multiplying or dividing by a negative number.
