Find kx+3y=k-3, 12x+ky=6 has infinite many solution |
|
Answer» Answer: K=6 Step-by-step EXPLANATION: infinite solutions a/a1=b/b1=c/c1 now a/a1=k/12 b/b1=3/k c/c1=k-3/6 by COMPARING a/a1=b/b1 we GET, 3/k=k-3/6 now, k square-3k-18=0 therefore by factorizing it we get k=6 and k=-3 by PUTTING value of k in equation we get the correct one which is k=6 |
