यदि \(x\in\mathbb{R}\) और (5-2x<1) है तो सही हल कौन सा है?
If \(x\in\mathbb{R}\) and (5-2x<1), which solution is correct?
Explanation opens after your attempt
Correct Answer
A. (x>2)
Concept
From (5-2x<1), we get (-2x<-4), hence (x>2). Reversing the sign for a negative coefficient is the key step.
Why this answer is correct
The correct answer is A. (x>2). From (5-2x<1), we get (-2x<-4), hence (x>2). Reversing the sign for a negative coefficient is the key step.
Exam Tip
(5-2x<1) से (-2x<-4) और (x>2) मिलता है। ऋणात्मक गुणांक पर चिन्ह पलटना मुख्य चरण है।
