Hi,

I am working with some annoyingly long equations that I want to simplify
by including one set of parameters in a constant (or function) A, and
another in B and so on.

You can easily do:

A = b+c+d+e

but what I want to do is the reverse:

b+c+d+e = A

and use this information to reduce the equations. Does anybody know how
to do this?
