    im not doing you fuckin' homework for you! I passed math 30 a while ago. But as for helping you. OK. Just multiply out all the brackets then group the alike variables then simplify. Sound easy? well it is.

    this is not rocket science....
    didn't you learn that multiply and division
    comes before addition and subtraction

    3x[4x-2y-(xy-1y+4x-4)-(4-xy)] =
    -3xy

    Me, I'm dishonest. And a dishonest man you can always trust to be dishonest. Honestly. It's the honest ones you want to watch out for. Because you can never predict when their going to do something incredibly stupid.
