Explanation opens after your attempt
Correct Answer

A. ([-1,6))

Step 1

Concept

Adding (6) gives \(-3\leq 3x<18\), then \(-1\leq x<6\). Apply the same operation to all parts of a compound inequality.

Step 2

Why this answer is correct

The correct answer is A. ([-1,6)). Adding (6) gives \(-3\leq 3x<18\), then \(-1\leq x<6\). Apply the same operation to all parts of a compound inequality.

Step 3

Exam Tip

(6) जोड़ने पर \(-3\leq 3x<18\) और फिर \(-1\leq x<6\) मिलता है। संयुक्त असमता में दोनों ओर समान क्रिया करें।
