(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
Correct Answer

A. (p=3)

Step 1

Concept

Twice the first equation must become the second equation. Hence (2p=6), so (p=3).

Step 2

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).

Step 3

Exam Tip

पहले समीकरण का (2) गुना दूसरा समीकरण बनना चाहिए। इसलिए (2p=6), अतः (p=3)।
