title: LaTeX: Align multiple align-environments
body: <p>I would like to align multiple align-environments as e.g.:</p>
  
  <pre><code>\documentclass{minimal}
  \usepackage{amsmath}
  
  \begin{document}
  \begin{align}
  wolf &amp;= animal \iff P(wolf)
  \end{align}
  blah blah
  \begin{align}
  a &amp;= b
  \end{align}
  \end{document}
  </code></pre>
  
  <p>The equal sign of formula (1) and (2) should be aligned with each other, i.e. alignment across several align-environments. Is something like this possible?</p>
  
  <p>Regards,
  Stefan</p>
