As reported in Ask SageMath question #46915:
gives an error message (unlike variants without assumptions, solving for a single variable, or adding a dummy equation).
It can be traced as follows: in
sage/symbolic/relation.py
the functionsolve
calls_solve_expression
to handle the single expression case. This (by default) uses the Maxima interface to create an initial list of solutionsX
, which is then filtered according toassumptions()
. This filtering assumes that each solution inX
is a single equation (it calls.lhs()
on elements ofX
), which is not true in the case of multiple variables.Component: symbolics
Keywords: solve, assumptions, domain
