Comment (by ajagekar.akshay):
{{{
sage: solve([x==5],[x])
}}}
returns {{{ [x == 5]}}} as expected, the changed code gets executed only
for system of equations.
Even for cases like
{{{
sage: solve([x==5,y==2],x,y)
}}}
maxima returns list of list as solution {{{ [[x == 5, y == 2]]}}}, so an
empty set is not returned. I also think returning error would be better
for unsolved equations. For TypeError, the parsing for {{{ solution_dict =
True}}}
can be fixed by checking length of variables list and adding appropriate
condition.
