    posted a picture because it was hard to write and draw. I am getting the wrong answer so i was wondering if my work is correct before i do the bounds?

    You should carry everything together, seems like you may have some sign errors

    and multiply through by -1/5 I think that's where your error is

    Yeah, just make sure you carry everything, and make square brackets so something like |dw:1442992434555:dw|

    So you know you're multiplying what and take the bounds with you to!
