I am using the solve command and the independent variables are in the form x=x. How can I output the solution as a list [set of solutions,independent variables]? The command select(z->symbol=symbol,S), where S is my set of solutions, does not work.

I have a rather large number of combinations to search and would like to use Task in order to take advantage of my multicore machine. The easiest way it seems to me to use Task to break up the total number of combinations into say, four pieces. Any one familiar with Task have any suggestions?
