indented slightly. IMO I don't like having them centered like the
usual Edit, Math, NumberWholeFormula method does.
I know LaTeX supports defining a user formatting code but I don't know
how to do that in LyX.
There are two relevant document class options:
* "fleqn" (flush left equation), which aligns the equation to the left.
Used by itself, though, it leaves the equation number on the right.
* "leqno" (left equation number), which puts the equation number on the
left. Used by itself, it centers the equation still.
BUT, if you use BOTH options, then you get what you want.
How to do it in LyX? Look at Document> Settings> Document Class. The
"Custom" field allows you to enter class options. In your case, you
could enter "fleqn,leqno". Any class options can be entered here.
However, LyX also has native support for this under Document> Settings>
Math Options. The Formula Numbering Side option is self-explanatory. You
would want "Left". This adds "leqno" behind the scenes. The other one is
the Indent Formulas checkbox. The tooltip explains what it does: It
indents instead of centering equations. So you can check that. If you
leave it at "Default", then it just adds "fleqn"; you can also, however,
control the indent here by selecting "Custom" and entering a length
(which gets set as the \mathindent).
This is all in the Math manual, under Help.
