Answer:
y = - 
Step-by-step explanation:
=
( cross- multiply )
4y = - 7 ( divide both sides by 4 )
y = - 
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=

Also y=

We can not divide with zero.
k-12=0
k=12For k= 12 equations have no solutions.
