Which is the number line solution of (\frac{x-10}{-4}\le 3)?असमानता (\frac{x-10}{-4}\le 3) का संख्या रेखा हल कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x\ge-2), closed dot at (-2) shaded right(x\ge-2), (-2) पर बंद बिंदु और दाईं ओर
Multiplying by (-4) reverses the sign to (x-10\ge-12), so (x\ge-2). In exams, reverse the sign when removing a negative denominator.(-4) से गुणा करने पर चिन्ह पलटकर (x-10\ge-12), इसलिए (x\ge-2)। परीक्षा में negative denominator हटाते समय sign reverse करें।
