    Suffice it to say, Fred only has 3/8 of John's money. We're looking for how much John originally had.

    Now if John gives Fred 6, his amount will become x - 6 because he loses 6, right? What happens to Fred's money?

    no. Where did you get that? haha His amount was originally 3/8 x so you just add 6 to that

    \[\Large \frac38x + 6\] more like :P

    So John's new amount is x - 6 and that thing up there ^ is Fred's new amount Apparently, with these new amounts, John has twice Fred's money. So, in equations, that'd be \[\Large x - 6 = 2\left[\frac38x + 6\right]\]

    It's just the fraction. But actually, you just distribute the 2 to the two terms inside the [] much like you did with the 6 earlier.

    It is. You can multiply everything by 8 to get rid of that denominator.

    lol that's just an alias I've been using. I'll multiply by 8, you do the rest. You CAN do it, because you did it before lol 8x - 48 = 6x + 96 Now solve it.
