I have a set of equations which in an aligned environment, with two equations per line. I want to give each equation its own unique label, something that looks like this
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align*}
a_{1} + a_{2} &= 0 \quad (A1), & a_{3} + a_{4} &= 0 \quad (A2) \\
b_{1} + b_{2} &= 0 \quad (A3), & b_{3} + b_{4} &= 0 \quad (A4) \\
c_{1} + c_{2} &= 0 \quad (A5), & c_{3} + c_{4} &= 0 \quad (A6)
\end{align*}
\end{document}
However, I would like to do this without manually assigning the labels A1, A2 etc at the end of each equation. So I was wondering if this is at all possible? Using the subequations environment allows you to give each line a label, but not each equation on each line. I should note that someone has already asked a similar question on the Latex website here, however, the equations don't vertically align correctly using tabularx.
