यदि समीकरण (4x+6y=18) और (2x+3y=k) के अनंत हल हों, तो (k) का मान क्या होगा?
If the equations (4x+6y=18) and (2x+3y=k) have infinitely many solutions, what is the value of (k)?
Explanation opens after your attempt
C. (9)
Concept
The first equation must be (2) times the second, so (k=9). For infinitely many solutions, keep all three ratios equal.
Why this answer is correct
The correct answer is C. (9). The first equation must be (2) times the second, so (k=9). For infinitely many solutions, keep all three ratios equal.
Exam Tip
पहला समीकरण दूसरे का (2) गुना होना चाहिए, इसलिए (k=9)। परीक्षा में अनंत हल के लिए तीनों अनुपात बराबर रखें।
