(ax+4y=12) और (3x+2y=6) के अनंत हल होने के लिए (a) का मान क्या है?
What is the value of (a) for (ax+4y=12) and (3x+2y=6) to have infinitely many solutions?
Explanation opens after your attempt
B. (a=6)
Concept
For infinitely many solutions, both equations must be proportional. The ratio of (4) and (2) is (2), so (a=6).
Why this answer is correct
The correct answer is B. (a=6). For infinitely many solutions, both equations must be proportional. The ratio of (4) and (2) is (2), so (a=6).
Exam Tip
अनंत हल के लिए दोनों समीकरण समानुपाती होने चाहिए। (4) और (2) का अनुपात (2) है, इसलिए (a=6) होना चाहिए।
