For (2x+3y=d) and (14x+21y=28) to have no solution, what condition is required on (d)?युग्म (2x+3y=d) और (14x+21y=28) में कोई हल न हो, इसके लिए (d) पर कौन-सी शर्त होगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (d\neq4)(d\neq4)
The coefficient ratio is (\frac{1}{7}). For no solution, (\frac{d}{28}\neq\frac{1}{7}), so (d\neq4).गुणांक अनुपात (\frac{1}{7}) है। कोई हल नहीं के लिए (\frac{d}{28}\neq\frac{1}{7}), इसलिए (d\neq4)।
