Hey,
The problem is the following : when using Solve[..,x], you must make sure that the x in the equation to solve is recognized as the x to solve. For your example, you must use a command like :
Solve[With[{x = x, t = t}, {den1 == 0, den2 == 0, den3 == 0,
den4 == 1}], {x, t}]
to show that the every time it finds a x or a t, it corresponds to the x and t specified in the Solve command.
There are a few warnings as regards convergence and so, but the results given are correct (I checked). What I haven't checked is the number of results expected ... I leave it to you ;-)
Hope it's been useful
Cheers,
Xavier
