असमता \(\frac{x-1}{3}\leq 2\) का हल कौन सा है?
What is the solution of \(\frac{x-1}{3}\leq 2\)?
Explanation opens after your attempt
A. \(x\leq 7\)
Concept
Multiplying by positive (3) does not change the sign and gives \(x-1\leq 6\). If the denominator is positive, the direction stays the same.
Why this answer is correct
The correct answer is A. \(x\leq 7\). Multiplying by positive (3) does not change the sign and gives \(x-1\leq 6\). If the denominator is positive, the direction stays the same.
Exam Tip
धनात्मक (3) से गुणा करने पर चिन्ह नहीं बदलता और \(x-1\leq 6\) मिलता है। हर धनात्मक हो तो दिशा वही रहती है।
