What is the solution of (2(x+3)-\frac{3x-1}{2}>7)?

Answer and explanation

Correct answer: \(x>1\)

Multiplying the inequality by 2 gives \(4x+12-(3x-1)>14\). On simplifying, \(x+13>14\), so \(x>1\). The option \(x\geq1\) is not correct because the original inequality is strict, and \(x=1\) does not satisfy it. Exam tip: multiplying an inequality by a positive number does not reverse its sign.
