    ohhh not sure on the first one but for the second one i rearranged them so the equations looked like this: 4y=x+8 2y=3x-6 can you see how i got that?

    i would then try to isolate one of the Ys. 4y=x+8 would turn into y=x+2. then plug it in. 2(x+2)=3x-6 do distruibutive property 2x+4=3x-6 -2x -2x 4=x-6 +6 +6 10=x

    So like 3(10) + 2y = 6 Y wasn't found?
