Explanation opens after your attempt
Correct Answer

B. \(-2x\le 6\)

Step 1

Concept

Multiplying by the negative number (-2) reverses the inequality sign. Therefore \(-2x\le 6\) is correct.

Step 2

Why this answer is correct

The correct answer is B. \(-2x\le 6\). Multiplying by the negative number (-2) reverses the inequality sign. Therefore \(-2x\le 6\) is correct.

Step 3

Exam Tip

ऋणात्मक संख्या (-2) से गुणा करने पर असमानता का चिह्न पलटता है। इसलिए \(-2x\le 6\) सही है।
