Problem:
Convert the following matrix to reduced row echelon form:
$\left(
\begin{array}{ccccc}
 -4 & -4 & 10 & -6 & -10 \\
 -8 & 4 & 4 & 0 & 5 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{ccccc}
 1 & 0 & -\frac{7}{6} & \frac{1}{2} & \frac{5}{12} \\
 0 & 1 & -\frac{4}{3} & 1 & \frac{25}{12} \\
\end{array}
\right)$
