समीकरणों (5x+ay=35) और (15x+18y=105) के अनंत हल होने के लिए (a) क्या होगा?
What will (a) be for the equations (5x+ay=35) and (15x+18y=105) to have infinitely many solutions?
Explanation opens after your attempt
C. (6)
Concept
For infinitely many solutions, (5/15=a/18=35/105) must hold. This gives (a=6).
Why this answer is correct
The correct answer is C. (6). For infinitely many solutions, (5/15=a/18=35/105) must hold. This gives (a=6).
Exam Tip
अनंत हल के लिए (5/15=a/18=35/105) होना चाहिए। इससे (a=6) मिलता है।
