समीकरणों (8x+ky=72) और (2x+7y=18) के अनंत हल होने के लिए (k) क्या होगा?
What will (k) be for the equations (8x+ky=72) and (2x+7y=18) to have infinitely many solutions?
Explanation opens after your attempt
C. (28)
Concept
The first equation must be (4) times the second. Therefore, (k=28).
Why this answer is correct
The correct answer is C. (28). The first equation must be (4) times the second. Therefore, (k=28).
Exam Tip
पहला समीकरण दूसरे का (4) गुना होना चाहिए। इसलिए (k=28) है।
