Changing the apperance of equation numbers with amsmath

I would like to move an equation number from its default position a little bit left.

(I learned to move an equation a little bit left from this site. But I could not locate any reference to move the equation number a little bit left. I searched this site with "move equation number".)

The following is the code that I am using.



Edited Question:

How can I align both equations and the equation numbers in the following code?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Please, see the question I linked in my edit; it should have all the necessary information. If not, please be more specific in your question. – egreg Sep 25 '11 at 21:03
@egreg Thank you. That reference is enough for me to move on. I do not understand how it works (yet) but I used your (new) align environment (instead of the equation environment) to get the desired effect. – Sony Sep 25 '11 at 21:24
It's hard to understand the role of \hskip{-6cm} in that code. If you want "left aligned" equations, consider the fleqn option to amsmath. – egreg Sep 25 '11 at 21:45
If you remove the \hspace{-6cm} the equation numbers will be aligned. – Peter Grill Sep 25 '11 at 21:49
I wanted to move an equation few cms (say 6 cms) to left and then reduce the gap between the equation and the equation number by a different amount (say 3 cms). I still do not have a solution. However, as I mentioned, I am playing with Andrew Stacey's answer to the question referred by egreg. Thanks to everyone who made comments. I truly appreciate this site. – Sony Sep 25 '11 at 22:28

1 Answer 1

A short answer to the edited question would be to use \mathrlap from the mathtools package, together with a \phantom to obtain the correct horizontal alignment:


Correct alignment of equation numbers

Regardless, as @egreg suggests in his comment, using \hspace for horizontal movement to some (arbitrary?) length of -6cm seems a bit bizarre.

Thank you very much. I deleted the edited question" as I found a reasonable solution by using Andrew Stacey's solution to the question posted by egreg. But your solution seems much nice. Therefore, I retyped the edited question". Sorry. – Sony Sep 25 '11 at 22:11
