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
Correct Answer

C. (9)

Step 1

Concept

The first equation must be (2) times the second, so (k=9). For infinitely many solutions, keep all three ratios equal.

Step 2

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.

Step 3

Exam Tip

पहला समीकरण दूसरे का (2) गुना होना चाहिए, इसलिए (k=9)। परीक्षा में अनंत हल के लिए तीनों अनुपात बराबर रखें।
