    5/8=(5/3)x-x
    5/8=(2/3)x
    multiply by reciprocal of 2/3 to get the x on its own and you are left with
    15/16=x

    Is it possible your equation is
    \frac{5}{8 - x} = \frac{5}{3x}?

    If so, multiply both sides of the equation by (8 - x) \cdot (3x) to get rid of those fractions. (And remind yourself at the end that x can't be either 0 nor 8.)

    5(3x) = 5(8 - x) <-- Now divide both sides by 5

    3x = 8 - x

    4x = 8

    x = 2
