Solve the inequality (3-\frac{2x+5}{7}\le \frac{1-x}{2}).असमानता (3-\frac{2x+5}{7}\le \frac{1-x}{2}) को हल करें।
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x\ge -9)(x\ge -9)
Multiplying by (14) gives (42-2(2x+5)\le 7(1-x)). This gives (32-4x\le 7-7x), so (3x\le -25).(14) से गुणा करने पर (42-2(2x+5)\le 7(1-x)) मिलता है। इससे (32-4x\le 7-7x), अतः (x\le -\frac{25}{3}) नहीं बल्कि (3x\le -25) है।
