Question: Solved symbolic system of equations, but failed simplified one

I'm a new user, and here is what puzzled me.

The system of two linear equations are solved below.  Great!

> solve({a-b*(m*qj+qI)-c*qj-v = 0, a-b*((m-1)*qj+2*qI)-c*qI-ld = 0}, {qj, qI});
               /     b m v - b m ld + c a - c ld + b a - b v 
               |qI = ---------------------------------------,
              <           2      2                    2      
               |         b  m + b  + 2 b c + c b m + c       
               \                                             

                       -b a + 2 b v - b ld - c a + c v\
                qj = - -------------------------------|
                        2      2                    2  >
                       b  m + b  + 2 b c + c b m + c  |
                                                      /
However, when I put a=100, b=1,c=1, and thought the problem became simpler,  Maple lost the solution.

> solve({100-m*qj-qI-qj-v = 0, 100-(m-1)*qj-3*qI-ld = 0}*{qj, qI});
Warning, solutions may have been lost

Can anyone tell me what was going on there?

Thanks,
