समीकरण (5x+7y=32) और (9x+13y=58) में (a) और (b) के अनुपातों की तुलना से क्या निष्कर्ष निकलेगा?

What conclusion follows from comparing the ratios of (a) and (b) in (5x+7y=32) and (9x+13y=58)?

Explanation opens after your attempt
Correct Answer

B. (59 \ne 7 / 13), इसलिए एक अद्वितीय हल / 13), so one unique solution

Step 1

Concept

Here \(5/9 \ne 7/13\), so the lines will intersect at one point. If the first two ratios differ, one unique solution is obtained.

Step 2

Why this answer is correct

The correct answer is B. \(5 / 9 \ne 7 / 13\), इसलिए एक अद्वितीय हल / 13), so one unique solution. Here \(5/9 \ne 7/13\), so the lines will intersect at one point. If the first two ratios differ, one unique solution is obtained.

Step 3

Exam Tip

यहां \(5/9 \ne 7/13\), इसलिए रेखाएं एक बिंदु पर कटेंगी। पहले दो अनुपात अलग हों तो एक अद्वितीय हल मिलता है।
