Hi all My first question is: I was looking at the code base of solveset.py and test_solveset.py. I found that on lines https://github.com/sympy/sympy/blob/master/sympy/solvers/tests/test_solveset.py#L39-L40 . Here why do we have consecutive declaration of `x`. I am not sure if that make any difference to use both of these lines.
I think first line can be removed without affecting the other ? Second question is: On the line https://github.com/sympy/sympy/blob/master/sympy/solvers/tests/test_solveset.py#L60 . Why have we allowed the inversion, i mean here `y` is just a `Symbol` with no assumptions like `positive=True, real=True` >>> x = Symbol('x', real=True) >>> y = Symbol('y', real=True) >>> inverse_real(Abs(x), y, x) (x, FiniteSet(-y, y)) # this is what it returns currently # i think it should be returned as it is. >>> y = Symbol('y', real=True, positive=True) >>> inverse_real(Abs(x), y, x) (x, FiniteSet(-y, y )) # currently this is returned which i think is correct Correct me if am wrong in my thinking at this point.
