I have three sub-equations and I want them to be left aligned and each to be numbered as (1a), (1b) and (1c). Since there are other equations too, I cannot change my existing packages or introduce a global setting which will disturb other equation. Here is what I have attempted.

  • Please make your code compilable (if possible), or at least complete it with documentclass..., the required usepackage's, begindocument, and enddocument. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem.

One could use only the align environment and therein the nonumber macro to suppress the tagging of lines one doesn't want to get a number:

Also for the future: Code seems to be easier to maintain if it is indented and line broken where it makes sense...



Another solution could be to nest an aligned environment inside of the align environment (this would get rid of the phantom= thingies):

If you use split within an align environment the & inside different split environments will actually line up.
I would use the aligned environment (also from amsmath) to split up the parts of the equation between the = symbols.

If you use split within an align environment the & inside different split environments will actually line up.
I would use the aligned environment (also from amsmath) to split up the parts of the equation between the = symbols.
