असमानता \(2x+7\le 3\) का हल क्या है?
What is the solution of the inequality \(2x+7\le 3\)?
Explanation opens after your attempt
A. \(x\le -2\)
Concept
Subtracting (7) gives \(2x\le -4\), so \(x\le -2\). Dividing by positive (2) does not change the sign.
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.
Exam Tip
(7) घटाने पर \(2x\le -4\), इसलिए \(x\le -2\)। धनात्मक (2) से भाग देने पर चिह्न नहीं बदलता।
