It doesn't solve it, and it can't be solved with the specification
you've described, because the first equation isn't identified. You
need "exclusion restrictions", i.e., variables that are in the female
household equation but not in the housing equation.

-help ivprob- has a basic description plus recommended further
reading for more details.
