To find that out we can use substitution on -2x+y=-3.
It should look like -2x+(4x-4)=-3.
After distributing the properties you should have 2x-4=-3.
Add 4 to both sides
2x=1
Divide 2 to both sides and x equals 0.5.
You can now plug x into either equation, I am going to use y=4x-4 for this example.
So y=4x-4 is now y=4(0.5)-4
y=2-4
y=-2
So the point that satisfies both equations is (0.5,-2)
