(2x+py=10) और (4x+6y=20) के अनंत हल होने के लिए (p) का मान क्या है?
What is the value of (p) for (2x+py=10) and (4x+6y=20) to have infinitely many solutions?
Explanation opens after your attempt
A. (p=3)
Concept
Twice the first equation must become the second equation. Hence (2p=6), so (p=3).
Why this answer is correct
The correct answer is A. (p=3). Twice the first equation must become the second equation. Hence (2p=6), so (p=3).
Exam Tip
पहले समीकरण का (2) गुना दूसरा समीकरण बनना चाहिए। इसलिए (2p=6), अतः (p=3)।
