Math & Science ⇒ Vertical aligned labels in enumerate for eq. systems?

[pczinder]

I have to make an enumerated list of systems of equations (i.e, each system should get a number in enumerating). How to align vertically the label of the item to the first equation, not at the center of the system of equations?

Can you give us aan example of such a system as a code example?

Thanks, Johannes. For example:

Code: Select all

         \begin{enumerate}[label=\emph{\alph*}),itemsep=5 mm]
             \item
                \(
                    \qquad\left.
                        \begin{aligned}
                            &(1) \quad 2x+3y=8 \\
                            &(2) \quad x-2y=-10
                        \end{aligned}
                    \right\}
                \)
             \item
                \(
                    \qquad\left.
                        \begin{aligned}
                            &(1) \quad 2x+3y=8 \\
                            &(2) \quad x-2y=-10 \\
                            &(3) \quad x+y=1
                        \end{aligned}
                    \right\}
                \)
        \end{enumerate}

I would like to put the item numbers a) and b) just before the first equations of both systems insted of the vertical center of the systems.

Thanks in advance!

What are you trying to achieve in the end? Is that supposed to be some kind of exam sheet? There might be a better solution available.
