असमानता \(x-y\leq 2\) को (y) के रूप में लिखने पर क्या मिलेगा?
What is obtained by writing \(x-y\leq 2\) in terms of (y)?
Explanation opens after your attempt
Correct Answer
A. \(y\geq x-2\)
Concept
From \(x-y\leq 2\), \(-y\leq 2-x\), so \(y\geq x-2\). The sign changes when dividing by a negative number.
Why this answer is correct
The correct answer is A. \(y\geq x-2\). From \(x-y\leq 2\), \(-y\leq 2-x\), so \(y\geq x-2\). The sign changes when dividing by a negative number.
Exam Tip
\(x-y\leq 2\) से \(-y\leq 2-x\), इसलिए \(y\geq x-2\) मिलता है। ऋणात्मक से भाग देने पर चिन्ह बदलता है।
