Which option gives the correct solution of the inequality \(2<3x+5<17\) ?

Answer and explanation

Correct answer: \(-1<x<4\)

Subtracting 5 from all three parts gives \(-3<3x<12\). Dividing by the positive number 3 yields \(-1<x<4\), without reversing the inequality signs. Option B is incorrect because the original inequality is strict at both ends, so equality is not included. Exam tip: with strict signs \(<\) or \(>\), the boundary values are excluded.
