simultaneous equation

Hi:

When I solve a simultaneous equation, the output looks as follows. How do I remove those ?1.? and the annoying wiggles in the superscript position in so many places.

With regards

trichy

Here is the whole thing. It's a small program... When I ran it anew, the superscript-wiggles are gone but the "1." persists. Thanks for the help.

x1 = 0.5 + (1/(4 t1)) (rsm - rsk);
x2 = 0.5 + (1/(4 t2)) (rLm - rLk);
x3 = 0.5 + (1/4) (rLk - n rsk);
x4 = 0.5 + (1/4) (rLm - n rsm);
ssk = a b x1 + (1 - a) g x3;
sLk = a (1 - b) x2 + (1 - a) g (1 - x3);

sLm = a (1 - b) (1 - x2) + (1 - a) (1 - g) (1 - x4);

Pim = ssm rsm + sLm rLm;
Pidsm = D[Pim, rsm]; PidLm = D[Pim, rLm];
