I assume you want to use Mathematica:

Reduce[inequality, var]

gives the complete solution for var x.

Solving for x(t) by hand, expand the inequality in the usual way, however,
notice you have two different solutions, depending wheter the lower part of
the fraction is negative or not, ie. the inequality sign changes its
direction or not.

That helps?
