What is the solution set of the inequality (3x-7<11)?

Answer and explanation

Correct answer: \(x<6\)

Given \(3x-7<11\), add 7 to both sides to get \(3x<18\). Dividing both sides by the positive number 3 does not reverse the inequality sign, so \(x<6\). The option \(x\leq 6\) is incorrect because equality is not included in the original inequality. Exam tip: reverse an inequality sign only when multiplying or dividing by a negative number.
