समीकरणों (7x+5y=22) और (14x+ay=51) का कोई हल न होने के लिए (a) क्या होगा?
What will (a) be for the equations (7x+5y=22) and (14x+ay=51) to have no solution?
Explanation opens after your attempt
C. (10)
Concept
For no solution, (7/14=5/a) and (22/51) must be different. This gives (a=10).
Why this answer is correct
The correct answer is C. (10). For no solution, (7/14=5/a) and (22/51) must be different. This gives (a=10).
Exam Tip
कोई हल नहीं के लिए (7/14=5/a) और (22/51) अलग होना चाहिए। इससे (a=10) मिलता है।
