For which (x) is (\frac{5-2x}{3}<\frac{x+7}{2}-4) true?किस (x) के लिए (\frac{5-2x}{3}<\frac{x+7}{2}-4) सत्य है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x>\frac{11}{7})(x>\frac{11}{7})
Multiplying by positive (6) gives (10-4x<3x-7). Hence (17<7x), so (x>\frac{17}{7}); none of the listed forms matches this exactly.धनात्मक (6) से गुणा करने पर (10-4x<3x-7) मिलता है। इससे (17<7x), अतः (x>\frac{17}{7}) होना चाहिए; विकल्पों में सही रूप नहीं है।
