For what values of k will the following pan of linear equations have infinitely many solutions?
`k x+3y-(k-3)=0`
`12 x+k y - k=0`

Explanation

as we know that `a_1x+b_1y+c_1 = 0`

`a_2x+b_2y+c_2=0`

has infinity solutions only when

`a_1/a_2 = b_1/b_2 = c_1/c_2`

so here, `k/12= 3/k = -(k-3)/(-k)`

`k/12= 3/k`

`k^2 = 36`

`k= +-6`
