Question

For which value of k does the pair of
equation given below has infinitely many
solutions?
kx + 3y - (k - 3) = 0
12x + ky = k = 0
​

Answer 1

As it has infinitely many solution

then a1/ a2= b1 / b2 = c1 / c2

therefore

k/12 = 3/ k

k^2 = 36

therefore k = 6

Answer 2

for infinite solution

a1/a2 =b1/b2

k/12= 3/k

k^2=36

k = 36^1/2

k =6

or

k= -6
