असमानता \(7-2x\le 1\) का हल क्या है?

What is the solution of the inequality \(7-2x\le 1\)?

Explanation opens after your attempt
Correct Answer

A. \(x\ge 3\)

Step 1

Concept

Subtracting (7) gives \(-2x\le -6\), then division by (-2) reverses the sign to \(x\ge 3\). Be careful with a negative coefficient.

Step 2

Why this answer is correct

The correct answer is A. \(x\ge 3\). Subtracting (7) gives \(-2x\le -6\), then division by (-2) reverses the sign to \(x\ge 3\). Be careful with a negative coefficient.

Step 3

Exam Tip

(7) घटाने पर \(-2x\le -6\), फिर (-2) से भाग देने पर चिह्न पलटकर \(x\ge 3\) होता है। ऋणात्मक गुणांक पर विशेष ध्यान दें।
