असमानता \(2\le \frac{x+3}{5}<3\) का संख्या रेखा पर हल कौन-सा है?

Which is the number line solution of \(2\le \frac{x+3}{5}<3\)?

Explanation opens after your attempt
Correct Answer

A. \(7\le x<12\)

Step 1

Concept

Multiplying by (5) and subtracting (3) gives \(7\le x<12\). In exams positive multiplication does not reverse the inequality sign.

Step 2

Why this answer is correct

The correct answer is A. \(7\le x<12\). Multiplying by (5) and subtracting (3) gives \(7\le x<12\). In exams positive multiplication does not reverse the inequality sign.

Step 3

Exam Tip

(5) से गुणा करके और (3) घटाकर \(7\le x<12\) मिलता है। परीक्षा में positive multiplication से inequality sign नहीं बदलता।
