असमानता \(\frac{x-1}{2}\le 3\) का संख्या रेखा पर हल कौन-सा है?
Which is the number line solution of \(\frac{x-1}{2}\le 3\)?
Explanation opens after your attempt
A. \(x\le 7\), (7) पर बंद बिंदु और बाईं ओर छाया\(x\le 7\), closed dot at (7) shaded left
Concept
Multiplying by (2) gives \(x-1\le 6\), so \(x\le 7\). In exams, multiplying by a positive number does not reverse the sign.
Why this answer is correct
The correct answer is A. \(x\le 7\), (7) पर बंद बिंदु और बाईं ओर छाया / \(x\le 7\), closed dot at (7) shaded left. Multiplying by (2) gives \(x-1\le 6\), so \(x\le 7\). In exams, multiplying by a positive number does not reverse the sign.
Exam Tip
दोनों ओर (2) से गुणा करने पर \(x-1\le 6\), इसलिए \(x\le 7\)। परीक्षा में धनात्मक गुणा करने पर चिन्ह नहीं बदलता।
