Question

find kx+3y=k-3, 12x+ky=6 has infinite many solution​

Answer 1

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
