    |x|-3>1/3x
    My first solution was 9/2x which is correct
    And second was 9/4x which is wrong because it's meant to be minus and the graphs show that too.
    But I can't seem to figure out where I'm going wrong with the working..
    Using this to work out second solution gives me a positive
    -(x-3)=1/3x

    generally speaking if |x|>a this means -a<x<a
    so the first thing you need to do is to isolate your |x| by moving the -3 to the other side then applying the formula I said
    after that, go through every side of the inequality separately. so work through -a<x separate and x<a separate then combine the result. That should give you your -9/4<x for one of them!

    your error is in mistaking |x|-3 for |x-3|
