A single equation:
\operatorname{erfc}(x) =
\frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
\frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
|
$ \operatorname{erfc}(x) = \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt = \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}} $ |
Multiple-line equation (default alignments):
\begin{align}
y &=& x + 2 \\
5x + 7z &=& 8y^2 + 2y - 5
\end{align}

$ \begin{align} y &=& x + 2 \\ 5x + 7z &=& 8y^2 + 2y - 5 \end{align} $ |
Multiple-line equation (user-set alignments, Right-Center-Left):
\begin{array}{rcl}
y & = & x + 2 \\
5x + 7z &=& 8y^2 + 2y - 5
\end{array}
