Problem:
Subtract the second matrix from the first:
$\left(
\begin{array}{ccc}
 -2 & \frac{42}{5} & \frac{24}{5} \\
\end{array}
\right)$
$\left(
\begin{array}{ccc}
 2 & -\frac{6}{5} & \frac{7}{5} \\
\end{array}
\right)$
Answer:
$\left(
\begin{array}{ccc}
 -4 & \frac{48}{5} & \frac{17}{5} \\
\end{array}
\right)$
