द्वि-असमीका \(-3<2x+1\le 9\) का समाधान समुच्चय ज्ञात कीजिए।
Find the solution set of the compound inequality \(-3<2x+1\le 9\).
Explanation opens after your attempt
A. \(-2<x\le 4\)
Concept
Subtracting (1) from all parts gives \(-4<2x\le 8\), so \(-2<x\le 4\). Apply the same operation to all three parts.
Why this answer is correct
The correct answer is A. \(-2<x\le 4\). Subtracting (1) from all parts gives \(-4<2x\le 8\), so \(-2<x\le 4\). Apply the same operation to all three parts.
Exam Tip
सभी पक्षों से (1) घटाने पर \(-4<2x\le 8\), इसलिए \(-2<x\le 4\)। परीक्षा में द्वि-असमीका में तीनों पक्षों पर समान क्रिया करें।
