What is (f) for no solution in (7x+fy=2) and (28x+20y=13)?युग्म (7x+fy=2) और (28x+20y=13) में कोई हल न होने के लिए (f) क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (f=5)(f=5)
To make the coefficient ratio (\frac{1}{4}), (f=5) is required. The different constant ratio gives no solution.गुणांक अनुपात (\frac{1}{4}) बनाने के लिए (f=5) चाहिए। स्थिर पद अनुपात अलग होने से कोई हल नहीं होगा।
