Append text to equation tags

0

I want to append the current section to equation tags, even if I use the tag command to override it. I would guess this entails creating some custom command like appendtag.

I know I can use numberwithin{equation}{section} to add the section number to the tags. I actually use
renewcommand{theequation}{arabic{section}--arabic{equation}}, because I prefer a dash over the dot.
However, if I use the tag command, I override the whole tag (as in equation (Ex) below). What I wish to do is just append some text, so that the equation tag reads (1-Ex).

documentclass{article}

usepackage{amsmath}

renewcommand{theequation}{arabic{section}--arabic{equation}}



begin{document}



section{First}



We have an untagged equation like

begin{equation}

    y = Xbeta + varepsilon,

end{equation}

with a second untagged equation like

begin{equation}

    E(varepsilon_i | X) = 0. tag{Ex}

end{equation}
