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.
Answer:
2 1/5 x 1 1/4 is greater than 1 1/4
Step-by-step explanation:
7+y
since y is unknown the value is not known
I think it's (h= $6.25) because if you divide all y's by x you will get 6.25 every time. so the answer is most likely $6.25
Answer:If you get stuck like this, I would suggest to try to find a reference guide/cheat sheet.
