I have problem to calculate exact answer.
Input:
{a, b} == Inverse[{{c, d}, {e, c}}.{{c, e}, {i, c}}].{c, e}
And output (I cant paste it here):

So you can see the problem (It doesnt subtract all like:
-r/(s+w)+(r+t)/(s+w) have to be t/(s+w)).
Second proble:
How i do that in Mathematica 4.2:
{a,b}=={c,d}
{w1,w2}={x1*c+x2*d,x3*c+x4*d}
and then solve (place beore symblic calculations)
H=w1*a+w2*b
??
