For the inequality \(4(x-2)>3x+7\), which of the following values of \(x\) is not a solution?

Answer and explanation

Correct answer: \(x=14\)

Simplifying the inequality gives \(4x-8>3x+7\), so \(x>15\). The values 16, 20, and 25 are greater than 15 and are therefore solutions, whereas \(x=14\) does not satisfy the condition. Exam tip: with a strict sign \(>\), the boundary value 15 itself is also excluded.
