असमानता \(\frac{2x+5}{-3}<1\) का संख्या रेखा पर हल क्या होगा?
What is the number line solution of \(\frac{2x+5}{-3}<1\)?
Explanation opens after your attempt
A. (x>-4), (-4) पर खुला बिंदु और दाईं ओर(x>-4), open dot at (-4) shaded right
Concept
Multiplying by (-3) reverses the inequality to (2x+5>-3), so (x>-4). In exams, reverse the sign when removing a negative denominator.
Why this answer is correct
The correct answer is A. (x>-4), (-4) पर खुला बिंदु और दाईं ओर / (x>-4), open dot at (-4) shaded right. Multiplying by (-3) reverses the inequality to (2x+5>-3), so (x>-4). In exams, reverse the sign when removing a negative denominator.
Exam Tip
(-3) से गुणा करने पर inequality reverse होकर (2x+5>-3) बनती है, इसलिए (x>-4)। परीक्षा में negative denominator हटाते समय चिन्ह पलटें।
