How can I place a brace symbol on the right covering several lines of equations?
I tried using \begin{cases} and \end{cases} but that adds the brace symbol on the left. 
I changed it to \begin{rcases} and \end{rcases} but that didn't work at all. 

An example of this problem can be seen in the attachment.

This post had a solution that worked when I tested it: https://stackoverflow.com/questions/3412813/multiline-brace-in-eqnarray/3413228

You can use something like this:
\[
\left.
\begin{array}{c}
x \\
y
\end{array} \right\} \Rightarrow z
\]

And you'll get something like this:

Apparently using "\left." and "\right\}" together lets you leave the left side blank.

That worked perfectly! Thank you very much!
