Which option gives the correct solution of \(-3(x+2)\ge2x-1\)?

Explanation opens after your attempt
Correct Answer

A. \(x\le-1\)

Step 1

Concept

From \(-3x-6\ge2x-1), we get \(-5x\ge5\), so \(x\le-1\). In exams reverse the sign while dividing by a negative coefficient.

Step 2

Why this answer is correct

The correct answer is A. \(x\le-1\). From \(-3x-6\ge2x-1), we get \(-5x\ge5\), so \(x\le-1\). In exams reverse the sign while dividing by a negative coefficient.

Step 3

Exam Tip

\(-3x-6\ge2x-1\) से \(-5x\ge5\), इसलिए \(x\le-1\)। परीक्षा में ऋणात्मक गुणांक से भाग देते समय चिह्न उलटें।
