समीकरणों (px-6y=18) और (2x-3y=9) के अनंत हल होने के लिए (p) का मान क्या है?
What is the value of (p) for (px-6y=18) and (2x-3y=9) to have infinitely many solutions?
Explanation opens after your attempt
B. (p=4)
Concept
For infinitely many solutions, the first equation must be (2) times the second. Hence (p=4).
Why this answer is correct
The correct answer is B. (p=4). For infinitely many solutions, the first equation must be (2) times the second. Hence (p=4).
Exam Tip
अनंत हल के लिए पहला समीकरण दूसरे का (2) गुना होना चाहिए। इसलिए (p=4)।
