Not sure anymore how I got to that x-solution, except that I just looked at the Google plot :-) In any case, I hope the sample code is useful, just eliminate the second solution.
For more complex equations, you need to wrap the MAXIMA-code into trigsimp(trigreduce(…)), so MAXIMA bothers simplifying the expression beyond the basics. When I have more time, I'll make a nice template for an "equation problem."
What else?
