Enough to glance at one of the manuals though: Doob's oft-cited "Gentle
Introduction to TeX" is the only one I have to hand and on p.43 you'll find
the answer.

Did you try it? Actually, you need to use \cr instead of \\, but with that
it works.
I would, however, recommend using the 'amsmath' & Co. packages (and reading
the manual); they provide better alternatives (for this and other math).
