I have a long equation with multiple equalities where I even have to split off the first equation.

  • Using 'multline' breaks the alignment of the equations
  • With 'align' or 'split' I have to pick an arbitrary point in the first line to align the others to. I also cannot align within \left(...\right).

Is there a way to do it automatically? I'm looking for something that looks like this picture in the end:

example equation

This is my code right now:


    &\leq t\pot+\tau\pot-C\sup_{s\leq\tau}|B_s+b|^p\\
    &\leq t\pot+\tau\pot-C\sup_{s\leq\tau}|B_s^p+b^p|\\
    &\leq t\pot+\tau\pot-C\sup_{s\leq\tau}\big||B_s|^p-|b|^p\big|\\
    &\leq t\pot+Cm^p+\tau\pot-CM_\tau^p\\

    You can align within left …\right with the \MTkillspecial command defined in § 3.6 (Paired Delimiters) of the mathtools documentation.

  • i assume you want just one equation number. you can use multined (requires mathtools) and use aligned for the lines after the first. Mar 14, 2017 at 17:07

How about this, with multline and aligned:

\usepackage{mathtools, nicefrac}


    &\leq t\pot+\tau\pot-C\sup_{s\leq\tau}\abs{B_s+b}^p \leq t\pot+\tau\pot-C\sup_{s\leq\tau}\abs{B_s^p+b^p}\\
    &\leq t\pot+\tau\pot-C\sup_{s\leq\tau}\abs[\big]{\abs{B_s}^p-\abs{b}^p}\leq t\pot+Cm^p+\tau\pot-CM_\tau^p


enter image description here


This is exactly what \MoveEqLeft from mathtools is for:

Sample output





    &\leq t\pot+\tau\pot-C\sup_{s\leq\tau}|B_s+b|^p\\
    &\leq t\pot+\tau\pot-C\sup_{s\leq\tau}|B_s^p+b^p|\\
    &\leq t\pot+\tau\pot-C\sup_{s\leq\tau}\big||B_s|^p-|b|^p\big|\\
    &\leq t\po


By default \MoveEqLeft starts the first line 2em to the left of the alignment point of the other lines. If you write \MoveEqLeft[5] this will be changed to 5em, and so on.

  • Though, I would not scale those () in the first line that much, big or Big is enough (I'm mostly allergic to left/right constructions)

  • @daleif Agreed - but this was to illustrate the OPs wish to be able to use \left...\right on such a line. Mar 15, 2017 at 7:15
