I need equation (1) followed by equation (1.a), (1.b), etc. But I am getting equation (1), then (2.a) (2.b), etc.

Because the method in egreg's answer is far more general. \addtocounter
You can use \ref :
\documentclass \usepackage \begin \begin\label \begin\tag<\ref> \mathrm = X + \sum\limits_^Y \\ \begin X &= ab \\ Y &= cd \end \end \end \end
Note how you can get the right vertical spacing instead of using equation and align with align nested in gather .
It's the same with llncs .
