\documentclass[]{article} \usepackage{amsmath} \begin{document} Here are two funny equations : \begin{align} \label{a label} a &= b, & c &= d. \end{align} Equation \eqref{a label}a is not the same as equation \eqref{a label}b. \end{document}
I need the equation numbers to be properly shown as (1a) and (1b), not as (1)a and (2)b like what is done by hand in this code. What should be the proper way of doing this?
