LaTeX beginner here. I am currently trying to reproduce the following equations (with labels and the corresponding tags) using the report class and amsmath:
Simply reproducing the equations without the braces is rather simple:
\begin{align}
\mathlarger{X_{ij}} &= \mathlarger{\frac{Y_iE_j}{Y}\left(\frac{t_{ij}}{\Pi_iP_j}\right)^{1-\sigma}} \tag{2-1} \label{eq:AvW1GE}\\
\nonumber \\
\mathlarger{(\Pi_i)^{1-\sigma}} &= \mathlarger{\sum_j \left(\frac{t_{ij}}{P_j}\right)^{1-\sigma} \frac{E_j}{Y}} \tag{2-2} \label{eq:AvW2GE}\\
\nonumber\\
\mathlarger{(P_j)^{1-\sigma}} &= \mathlarger{\sum_i \left(\frac{t_{ij}}{\Pi_i}\right)^{1-\sigma} \frac{Y_i}{Y}} \tag{2-3} \label{eq:AvW3GE}
\end{align}
However, adding the curly braces with text is more difficult for me. So far, I have tried to use "cases" with "aligned", providing at best mixed results, at least when it comes to adding the second brace, and error messages when adding tags or labels.
I would appreciate any help!
Best, Noah
