    As the LHS side is negative, the numerator and denominator must be of different signs.

    There are two scenarios thus:

    1) Abs(-4x) is negative, 3-x is postive

    2) Abs-4x is positive, 3-x is negative

    As the abs function is always positive, then 3-x must always be negative

    3-x<0

    3<x
