How to properly label two aligned equations on the same line? - LaTeX Stefan Kottwitz. There's support for side by side and alignment in general, just mixing in sub-numbering in aligned environments is not so common and less supported by default.

Equation latex label. How to reference an equation by label in my final output? - LaTeX I think that without packages, LaTeX does not know whether you are referencing a figure, a table, or an equation, etc. A hackish solution is to rely on the label name.
