असमानता \(4x-7\le 9\) का हल क्या है?
What is the solution of \(4x-7\le 9\)?
Explanation opens after your attempt
A. \(x\le 4\)
Concept
Adding (7) gives \(4x\le 16\), and dividing by (4) gives \(x\le 4\). Dividing by positive (4) keeps the sign unchanged.
Why this answer is correct
The correct answer is A. \(x\le 4\). Adding (7) gives \(4x\le 16\), and dividing by (4) gives \(x\le 4\). Dividing by positive (4) keeps the sign unchanged.
Exam Tip
(7) जोड़ने पर \(4x\le 16\) और (4) से भाग देने पर \(x\le 4\) मिलता है। धनात्मक (4) से भाग देने पर चिन्ह नहीं बदलता।
