… and all isn’t fresh in sympy‘s realm.
Full details in this ask.sagemath.org question <https://ask.sagemath.org/question/64344/solving-a-system-of-linear-equations-with-complex-numbers-yields-false-solution/?answer=64363#post-id-64363>. TL:DR : a (linear) system of equations, perfectly solved by Sage’s default solver (i. e. Maxima’s), gets a wrong answer when one of its variables is replaced by the I (imaginary unit) constant. The problem can be traced to Maxima by reproducing it in Maxima. The same system (with the I constant) seems unsolvable by sympy (no return after 15 minutes…). Giac doesn’t give an answer, anf Fricas returns the same thing as Maxima. Ouch !
