How to align an equation with equations inside of a begin{case}












2














I have the following code



documentclass{article} 
usepackage{amsmath}
usepackage{mathtools}

begin{document} begin{align*}
Omega &= begin{cases}
X &= Y\
W &= X
end{cases}\
Z &= W end{align*} end{document}


Which generates

          Almost there... here's a minor adjustment that uses eqparbox to aid in the measurement for contents across cells within the align and cases.



          enter image description here



          documentclass{article} 

          usepackage{amsmath,eqparbox}

          begin{document}

          begin{align*}
          Omega = begin{cases}
          abc & = eqmakebox[RHS][l]{$defgh$} \
          i & = eqmakebox[RHS][l]{$j$}
          end{cases} kern-nulldelimiterspace & \
          klmno = eqmakebox[RHS][l]{$pqrstuv$} &
          end{align*}

          end{document}


          Since the alignment is chosen on the right-hand side of entire structure, a minor spacing correction for the right-hand side of cases is necessary.



          If needed, you can use eqmakebox[LHS] for the left-hand side(s) as well.
