Correct Answer

A. \(x\le -2\)

Subtracting (7) gives \(2x\le -4\), so \(x\le -2\). Dividing by positive (2) does not change the sign.

Step 2

Why this answer is correct

The correct answer is A. \(x\le -2\). Subtracting (7) gives \(2x\le -4\), so \(x\le -2\). Dividing by positive (2) does not change the sign.

(7) घटाने पर \(2x\le -4\), इसलिए \(x\le -2\)। धनात्मक (2) से भाग देने पर चिह्न नहीं बदलता।
