असमानता \( -1\leq \frac{x+3}{2}<5 \) का हल क्या है?
What is the solution of \( -1\leq \frac{x+3}{2}<5 \)?
Explanation opens after your attempt
A. \( -5\leq x<7 \)
Concept
Multiplying by positive (2) gives \(-2\leq x+3<10\), then subtracting (3) gives \(-5\leq x<7\). Positive multiplication does not change direction.
Why this answer is correct
The correct answer is A. \( -5\leq x<7 \). Multiplying by positive (2) gives \(-2\leq x+3<10\), then subtracting (3) gives \(-5\leq x<7\). Positive multiplication does not change direction.
Exam Tip
धनात्मक (2) से गुणा करने पर \(-2\leq x+3<10\) और (3) घटाने पर \(-5\leq x<7\) मिलता है। धनात्मक गुणन में दिशा नहीं बदलती।
