यदि (2x+ky=18) और (6x+12y=54) अनंत समाधान देते हैं, तो (k) का मान क्या है?
If (2x+ky=18) and (6x+12y=54) give infinitely many solutions, what is the value of (k)?
Explanation opens after your attempt
C. (4)
Concept
The second equation is (3) times the first, so (3k=12) and (k=4). For infinite solutions, the lines must be coincident.
Why this answer is correct
The correct answer is C. (4). The second equation is (3) times the first, so (3k=12) and (k=4). For infinite solutions, the lines must be coincident.
Exam Tip
दूसरा समीकरण पहले का (3) गुना है, इसलिए (3k=12) और (k=4)। अनंत समाधान के लिए रेखाएं संपाती होनी चाहिए।
