If ( \frac{7-3x}{4}<\frac{x+1}{2} ), which is the correct solution?

Answer and explanation

Correct answer: \(x>1\)

Multiplying both sides by the positive number 4 does not change the inequality sign: \(7-3x<2x+2\). Hence \(5<5x\), so \(x>1\). Option \(x\geq1\) is not correct because at \(x=1\), both sides are equal, whereas the question has a strict inequality, \(<\). Exam tip: Reverse an inequality sign only when multiplying or dividing by a negative number.
