समीकरण (2x+my=14) और (8x+20y=56) के अनंत हल होने के लिए (m) का मान क्या होगा?
What will be the value of (m) for (2x+my=14) and (8x+20y=56) to have infinitely many solutions?
Explanation opens after your attempt
A. (5)
Concept
For infinitely many solutions, (2/8=m/20=14/56) must hold. Therefore, (m=5).
Why this answer is correct
The correct answer is A. (5). For infinitely many solutions, (2/8=m/20=14/56) must hold. Therefore, (m=5).
Exam Tip
अनंत हल के लिए (2/8=m/20=14/56) होना चाहिए। इसलिए (m=5) है।
