Paula,
I think algsubs cannot recognize a "buried" pattern. I tried to
rewrite your eqation as:
y:=a/(a+b)*c
and then
algsubs(a/(a+b)=x,y);
But that failed to! I think what happens here is that when you enter
your equation,
maple stores it as
y=a*c/(a+b)
and cannot find the unique "pattern" a/(a+b) in taht expression. This
seems to be a problem with algsubs. Perhaps someone else can find a
solution.

It looks like y = x * c or x = y/c. What am I missing?
