sympy.solvers.solvers.solve should also allow frozenset to hold equations

The patch already contains the additional tests for solve for lists, sets
and frozensets. See line 253-261 i

solve((x-y,y),x) is None

No new opinions so far here. What about having an argument to solve for
defining the result type?
Candidates in my opinion would be:
- ==1 var

Is there a reason not to make the hint assume_positive rather than
assume_pos_real?
In logcombine(), it's called assume_pos_real because for the combination
rules to be valid,

I see, you just put it as a doctest. I would prefer to see them as regular
tests (sympy/solvers/tests/test_solve.py), since y

There's also the roots() style, which is a dictionary of solution:
multiplicity pairs (this only works for polynomial equations).
How would just a list or tuple o

This is what I wanted to achieve, i.e. to have a model for rational
functions similar to the model we have for polynomials: DMF (SMF) class for
low-lev

Even a simple implementation that can only do the basics like addition and
multiplication would be useful, because I could replace my tuple model with
