follow-up on solving a set of symbolic equations



First, thanks for all the help. As a first time user I can say that having 
the input and output lines in maxima indexed by c1,c2   d1,d2  can be a 
definite pitfall. It certainly was to me since I had a coefficient called 
"c1" .  I suppose it would be nice to index the in and out lines 
differently, but, now that I understand what's going-on I can work around 
it. One persons email (Thank you Barton Willis) mentioned the re-assigment 
of the in and out line indexing and that looks like a good way to go for me.

And, then the follow-up question. If I solve a set of equations like the 
example in the documentation (from "Introduction to MACSYMA"
) below:

(C6) a + b*c=1;

(D6)                              b C + a = 1
(C7) b - a*c=0;

(D7)                              b - a C = 0
(C8) a+b=5;

(D8)                               b + a = 5
(C9) solve([d6,d7,d8],[a,b,c]);

            25 SQRT(79) %I + 25      5 SQRT(79) %I + 5      SQRT(79) %I + 1
(D9) [[a = -------------------, b = -----------------, C = ---------------],
            6 SQRT(79) %I - 34       SQRT(79) %I + 11             10

             25 SQRT(79) %I - 25      5 SQRT(79) %I - 5        SQRT(79) %I - 1
        [a = -------------------, b = -----------------, C = - 
---------------]]
             6 SQRT(79) %I + 34       SQRT(79) %I - 11               10


How can I separately access the variables a,b and c ?



Thanks
