    How would you solve it if it were an equality?

    If you had: \[\frac{4}{x-3} - \frac{1}{2x} = 0\] What would your first step be.

    That's one way to start. Lets go with that since it's your intuition

    The overall strategy is to solve the relation the same way you would solve an equality. And just remember if you multiply (or divide) by a negative you change the direction of the relation.
