### Description

sage: solve([x**2-1>0,x>0],x,solution_dict=True) [{1: x}]

Probably the correct result from Maxima is mistranslated. Of course inequalities expressing interval results should not be converted to dict.

**Note:**See TracTickets for help on using tickets.

Another mistranslation, found when fooling around #21789 :

Such "solutions" inverting (part of) variable-value couples, can't be used for further substitution. This may be a cause of #21789...

Note that :

This hints at a mishandling of "variable-lookalike" constants. Deep in the Maxima interface...
