When x appears both in and outside of a trancendental function,
in the same equation, as it does here, there is no algebraic way 
of solving it.  You can only get an approximate answer by a 
calculator, or iterative means.  

With a TI-84 the two solutions are approximately

0.44754216 and -1.980974.  Do you need calculator help? Or are
you studying solving by iteration, something like Newton's 
approximation method?
