Comment(by leif):
Yep:
{{{
* ``solution_dict`` - bool (default: False); if True or non-zero,
return a list of dictionaries containing the solutions. If there
are no solutions, return an empty list (rather than a list
containing an empty dictionary). Likewise, if there's only a
single solution, return a list containing one dictionary with
that solution.
}}}
A doctest for a similar case got deleted by a reviewer, which still works
though:
{{{
sage: solve([x+y==6, x-y==4], x, y, solution_dict=-1)
[{y: 1, x: 5}]
}}}
And also the following works as expected:
{{{
sage: solve([x==0],x,solution_dict=True)
[{x: 0}]
}}}
(Sage 4.7.1.{alpha2,rc0})
