I have a formula which is given by equation say
$$x_\pm = .....$$
and which I would like to call $(6.7)_\pm$. Sometimes
I will refer to $(6.7)_\pm$ and sometimes to $(6.7)_+$,
or $(6.7)_-$. Is there a way to do it in the usual
\label - \ref way completely avoiding typing (6.7)?
Also I want it to be consistent with hyperref package
