यदि \(\frac{4x-1}{3}-\frac{x+2}{9}\ge x+1\), तो (x) का हल क्या है?
If \(\frac{4x-1}{3}-\frac{x+2}{9}\ge x+1\), what is the solution for (x)?
Explanation opens after your attempt
A. \(x\ge7\)
Concept
Multiplying by positive (9) gives (3(4x-1)-(x+2)\ge9x+9). Thus \(2x\ge14\), so \(x\ge7\).
Why this answer is correct
The correct answer is A. \(x\ge7\). Multiplying by positive (9) gives (3(4x-1)-(x+2)\ge9x+9). Thus \(2x\ge14\), so \(x\ge7\).
Exam Tip
धनात्मक (9) से गुणा करने पर (3(4x-1)-(x+2)\ge9x+9) मिलता है। इससे \(2x\ge14\), अतः \(x\ge7\)।
