I would like my output to look like, which fits easily on an A4 page:
lots of text from left margin x = 1 lots of text to right margin 34x + y = 5x + y
This is what I have tried:
\documentclass{amsart} \begin{document} \begin{flalign*} & \text{lots of text from left margin} & x &= 1 & \text{lots of text to right margin} \\ && u + 2v + w + 34x + y + 4z &= 3u + v + 2w + 5x + y + 3z \\ \end{flalign*} \end{document}
