Which pair will give a unique solution because of different coefficient ratios?किस युग्म की रेखाएं अलग गुणांक अनुपातों के कारण एक अद्वितीय समाधान देंगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (5x-2y=11), (x+y=7)(5x-2y=11), (x+y=7)
For (5x-2y=11) and (x+y=7), (\frac{5}{1}\neq\frac{-2}{1}), so the lines intersect. Different coefficient ratios give a unique solution.(5x-2y=11) और (x+y=7) में (\frac{5}{1}\neq\frac{-2}{1}), इसलिए रेखाएं प्रतिच्छेदी हैं। अलग गुणांक अनुपात अद्वितीय समाधान देता है।
