    Maple 10: solve() and complex numbers

    Hi all
    i've been trying to solve 2 equation with two variables in Maple 10. I got 3 solutions which are complex,
    i.e. a list A:=[[ x = ... , y = ...], [...], [...]].
    now, A[1,1] gives me the x of the first solution, and I want the real part of it. But when I write Re(A[1,1]) it gives as an answer
    R(x) = R(...). the problem is that afterwards I need to use this number (for emaple, in pointplot() ), and Maple doesn't let me.
    How do I extract the number itself from Re(A[1,1]) (and not a string)?
    thanks in advance

    Could you post some of your code, if it's not too long, as I'm having a hard time visualizing your problem. Thanks.
