What is the solution of the inequality \(3x+10<x+22\)?

Answer and explanation

Correct answer: \(x<6\)

Subtracting \(x\) from both sides gives \(2x+10<22\). Subtracting 10 and then dividing by 2 gives \(2x<12\), so \(x<6\). Therefore, option A is correct. Option B incorrectly reverses the inequality sign; no multiplication or division by a negative number occurs here. Exam tip: Reverse an inequality sign only when multiplying or dividing by a negative number.
