If the value of \(4x-7\) is not greater than \(13\), which is the correct solution for \(x\)?

Answer and explanation

Correct answer: \(x\leq 5\)

“Not greater than” means \(\leq\), so the inequality is \(4x-7\leq 13\). Adding 7 to both sides gives \(4x\leq 20\), and dividing by 4 gives \(x\leq 5\). Therefore, option C is correct. Option D is incorrect because it excludes \(x=5\), even though \(4(5)-7=13\). Exam tip: interpret “not greater than” as \(\leq\) and “not less than” as \(\geq\).
