Left aligned equations

In my document, I have a block of 3 equations that need to be aligned on the = sign. This is the code:



 documentclass[a4paper, 11pt]book
 usepackageamsmath
 begindocument

 beginalignat2
 &textxxxxxxx1 &&= 1/y \
 &textx2 &&=y \
 &textx3 &&=y^2+x2
 endalignat

enddocument


However, I'd also like this block of equations to be left-aligned. Instead, with that code, it is centered on the page.



In a related post, someone suggested to use fleqn as a document class. Nevertheless, I cannot use that, because some of the equations in my document have to be centered, not all of them have to be left-aligned.

  • You want just these three to be aligned on the left margin, but still numbered at the right margin?

  • Yes, exactly. All equations in my document are numbered at the right margin, but I do not want all of them to be aligned at the left margin

it is not very clear to me what you like to obtain, so below are two options which cross my mind:



  • in the first is used flalign math environment from the amsmath package

  • in second the gather environment (also from amsmat) is enclosed in fleqn environment proviedad by he package nccmath

enter image description here



(red lines indicate text borders)



 documentclass[a4paper, 11pt]book
 usepackageamsmath
 usepackagenccmath

 %---------------- show page layout. don't use in a real document!
 usepackageshowframe
 renewcommandShowFrameLinethickness0.15pt
 renewcommand*ShowFrameColorcolorred
 %---------------------------------------------------------------%

 begindocument

 beginflalign
 textxxxxxxx1 &= 1/y &\
 textx2 &= y &\
 textx3 &= y^2+x2 &
 endflalign

 or

 beginfleqn
 begingather
 textxxxxxxx1 = 1/y \
 textx2 = y \
 textx3 = y^2+x2
 endgather
 endfleqn

 enddocument


edit:
from your comments follows that you like to have something like this:

A solution not really completely automated, but you can do your job till find a completed automated method:
