Please help me to prove the following result:
Let \(\displaystyle R\) be a ring with \(\displaystyle 1\) and \(\displaystyle \mathcal{F}\) a family of simple left \(\displaystyle R\) modules.
Let \(\displaystyle M=\oplus_{S\in \mathcal{F}} S\) and suppose that \(\displaystyle T\) is a simple submodule of \(\displaystyle M\).
Show that \(\displaystyle T\cong S\) for some \(\displaystyle S\in \mathcal{F}\).
Thanks
