समीकरण (2x-5y+1=0) और (3x+y-4=0) के लिए \(a_1/a_2\) और \(b_1/b_2\) की तुलना से क्या मिलेगा?
For (2x-5y+1=0) and (3x+y-4=0), what follows from comparing \(a_1/a_2\) and \(b_1/b_2\)?

C. एक अद्वितीय हलOne unique solution
Concept
Here (2/3 \ne (-5)/1), so there is a unique solution. If the first two ratios differ, the third ratio need not be checked.
Why this answer is correct
The correct answer is C. एक अद्वितीय हल / One unique solution. Here (2/3 \ne (-5)/1), so there is a unique solution. If the first two ratios differ, the third ratio need not be checked.
Exam Tip
यहां (2/3 \ne (-5)/1), इसलिए unique solution है। पहले दो अनुपात अलग हों तो तीसरा अनुपात देखने की जरूरत नहीं होती।
