यदि \(x\in\mathbb{R}\), तो \(6-2x\ge x+9\) का हल कौन सा है?
If \(x\in\mathbb{R}\), which is the solution of \(6-2x\ge x+9\)?
Explanation opens after your attempt
B. \(x\le-1\)
Concept
Simplification gives \(-3x\ge3\). Dividing by a negative number reverses the sign, so \(x\le-1\).
Why this answer is correct
The correct answer is B. \(x\le-1\). Simplification gives \(-3x\ge3\). Dividing by a negative number reverses the sign, so \(x\le-1\).
Exam Tip
सरलीकरण से \(-3x\ge3\) मिलता है। ऋणात्मक संख्या से भाग देने पर चिन्ह बदलता है, इसलिए \(x\le-1\)।
