समीकरण (5x+ky=35) और (x+4y=7) के अनंत हल होने के लिए (k) का मान क्या होगा?
What is the value of (k) for (5x+ky=35) and (x+4y=7) to have infinitely many solutions?
Explanation opens after your attempt
C. (20)
Concept
The first equation must be (5) times the second, so (k=20). A common multiplier makes both lines coincident.
Why this answer is correct
The correct answer is C. (20). The first equation must be (5) times the second, so (k=20). A common multiplier makes both lines coincident.
Exam Tip
पहला समीकरण दूसरे का (5) गुना होना चाहिए, इसलिए (k=20)। समान गुणक से दोनों रेखाएं संपाती होती हैं।
