Which is the correct number line solution of (\frac{5-4x}{-2}>3)?असमानता (\frac{5-4x}{-2}>3) का संख्या रेखा पर सही हल कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x>\frac{11}{4}), open dot at (\frac{11}{4}) shaded right(x>\frac{11}{4}), (\frac{11}{4}) पर खुला बिंदु और दाईं ओर
Multiplying by (-2) reverses the sign to (5-4x<-6), so (x>\frac{11}{4}). In exams, reverse the inequality when removing a negative denominator.(-2) से गुणा करने पर चिन्ह पलटकर (5-4x<-6), इसलिए (x>\frac{11}{4})। परीक्षा में negative denominator हटाते समय inequality reverse करें।
