यदि (3x+2y=p) और (6x+4y=20) की रेखाएं अनंत समाधान देती हैं, तो (p) क्या है?
If (3x+2y=p) and (6x+4y=20) give infinitely many solutions, what is (p)?
Explanation opens after your attempt
B. (10)
Concept
For infinitely many solutions, the second equation must be (2) times the first. Therefore (2p=20) and (p=10).
Why this answer is correct
The correct answer is B. (10). For infinitely many solutions, the second equation must be (2) times the first. Therefore (2p=20) and (p=10).
Exam Tip
अनंत समाधान के लिए दूसरा समीकरण पहले का (2) गुना होना चाहिए। इसलिए (2p=20) और (p=10)।
