Answer 2

Basically, you use the second equation to get y= -2x+8. Then you plug in your y(-2x+8) into the first equation to get x(which is 4). Then you plug in 4 into the second equation 2(4)+y=8 to get y(which is 0).

Answer 3

It's asking me something about whether the lines or coincident or parallel?
