असमानता \(x-y\le 2\) को (y) के रूप में लिखने पर क्या मिलेगा?
When \(x-y\le 2\) is written in terms of (y), what is obtained?
Explanation opens after your attempt
Correct Answer
A. \(y\ge x-2\)
Concept
From \(x-y\le 2\), \(-y\le 2-x\), and reversing the sign gives \(y\ge x-2\). Do not forget to reverse the sign when dividing by a negative.
Why this answer is correct
The correct answer is A. \(y\ge x-2\). From \(x-y\le 2\), \(-y\le 2-x\), and reversing the sign gives \(y\ge x-2\). Do not forget to reverse the sign when dividing by a negative.
Exam Tip
\(x-y\le 2\) से \(-y\le 2-x\) और चिन्ह बदलकर \(y\ge x-2\) मिलता है। ऋणात्मक से भाग देने पर चिन्ह पलटना न भूलें।
