If (x+ky=8) and (2x+6y=16) give infinitely many solutions, what is the value of (k)?यदि (x+ky=8) और (2x+6y=16) अनंत समाधान देते हैं, तो (k) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (3)(3)
The second equation is (2) times the first, so (2k=6) and (k=3). For infinite solutions, the lines must be coincident.दूसरा समीकरण पहले का (2) गुना है, इसलिए (2k=6) और (k=3)। अनंत समाधान के लिए रेखाएं संपाती होनी चाहिए।
