Hi. I have a question. I have a bunch of symbolic equations and I want to write a variable in terms of some others. Can I do that and how?

An example:

a=b+c
c=b+d+a

How to solve for b in terms of d?

Answer should be:

b=-d/2

Or b in terms of a and c?

Answer should be:

b=a-c

I think you shuld wait until the symbolic "solve" will be implemented as a plugin (from Xcas I suppose). It is not available for desktop configurations yet.

Thank you.
