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
Correct Answer

A. \(-6<x\leq 4\)

Step 1

Concept

Subtracting (5) gives \(-12<2x\leq 8\), then \(-6<x\leq 4\). Apply the same operation to every part of a compound inequality.

Step 2

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.

Step 3

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।
