    Plug in y=5x-5 (-5x+y=-5 add 5x to both sides) for y in the second equation: -4x+2(5x-5)=2 Think you can do that? Then, just plug in the value you get for x into y=5x-5 and solve for y.

    my apologies, I'm getting help on my own math lol so... -4x+2(5x-5)=2 -4x+10x-10=2 Think you can take it from there?

    \(-5x+y=-5\) \(-4x+2y=2\) change (Multiply with - ) \(+4x-2y=-2\) Then, \(-5x+y=-5\) \(+4x-2y=-2\) solution: \(x-y=7\) option \(D\) \(2-(-5)=7\)

    Time up: \(-5x+y=-5\) \(+4x-2y=-2\) Solution: \(-x-y=-7\) substitute, Option D.(2,5) \(2 \) = \(x\) \(5 \) = \(y\) Substitute: \(-x-y=-7\) \(-2-5~=~7\) \(you~are~right~!!\) @mckenzieandjesus
