असमानता \(7-2x\le 1\) का हल क्या है?
What is the solution of the inequality \(7-2x\le 1\)?
Explanation opens after your attempt
A. \(x\ge 3\)
Concept
Subtracting (7) gives \(-2x\le -6\), then division by (-2) reverses the sign to \(x\ge 3\). Be careful with a negative coefficient.
Why this answer is correct
The correct answer is A. \(x\ge 3\). Subtracting (7) gives \(-2x\le -6\), then division by (-2) reverses the sign to \(x\ge 3\). Be careful with a negative coefficient.
Exam Tip
(7) घटाने पर \(-2x\le -6\), फिर (-2) से भाग देने पर चिह्न पलटकर \(x\ge 3\) होता है। ऋणात्मक गुणांक पर विशेष ध्यान दें।
