### Multi-line right brace

Hey guys, I'm writing a 3-line equation and need a brace to join them all on the right side. I know I can use "\begin{cases}" but that gives me a brace on the left side. What do you propose?

Take a look at the empheq package from the mh bundle.

Best regards and welcome to the board

What's wrong with this?
1. \begin{equation}
2. f(x) = \left\{
3. \begin{array}
4. 1 & x > 0 \\
5. 0 & x = 0 \\
6. -1 & x < 0
7. \end{array}
8. \right.
9. \end{equation}

It still has a brace on the left side. And the OP wants a brace at the right side. Furthermore it is unclear if the OP wants that brace beside equations which are numbered separately.

I don't think he wants to number them, if what he writes is correct. (I'm taking the fact that he states he could use the {cases} environment into consideration.) He could do it this way:

1. \left.\begin{aligned}
2. Equation 1 \\
3. Equation 2 \\
4. Equation 3
5. \end{aligned}\right\rbrace

2. f(x) = \left\{
3. \begin{array}{cc}
4. 1 & x > 0 \\
5. 0 & x = 0 \\
6. -1 & x < 0
7. \end{array}
8. \right.
9. \end{equation}
