यदि \(x\in\mathbb{R}\) और \(-7<2x+5\leq 13\) है तो (x) का सही हल कौन सा है?
If \(x\in\mathbb{R}\) and \(-7<2x+5\leq 13\), which solution for (x) is correct?
Explanation opens after your attempt
A. \(-6<x\leq 4\)
Concept
Subtracting (5) gives \(-12<2x\leq 8\), then \(-6<x\leq 4\). Apply the same operation to every part of a compound inequality.
Why this answer is correct
The correct answer is A. \(-6<x\leq 4\). Subtracting (5) gives \(-12<2x\leq 8\), then \(-6<x\leq 4\). Apply the same operation to every part of a compound inequality.
Exam Tip
(5) घटाने पर \(-12<2x\leq 8\) और फिर \(-6<x\leq 4\) मिलता है। संयुक्त असमता में हर भाग पर समान क्रिया करें।
