Problem:
Subtract the second matrix from the first:
$\left(
\begin{array}{cccc}
 -\frac{31}{5} & -\frac{12}{5} & -\frac{3}{2} & -\frac{13}{2} \\
 -\frac{37}{5} & -\frac{14}{5} & \frac{7}{5} & -8 \\
\end{array}
\right)$
$\left(
\begin{array}{cccc}
 -\frac{38}{5} & -\frac{41}{5} & -\frac{16}{5} & -\frac{18}{5} \\
 -\frac{47}{10} & -\frac{48}{5} & \frac{69}{10} & -\frac{77}{10} \\
\end{array}
\right)$
Answer:
$\left(
\begin{array}{cccc}
 \frac{7}{5} & \frac{29}{5} & \frac{17}{10} & -\frac{29}{10} \\
 -\frac{27}{10} & \frac{34}{5} & -\frac{11}{2} & -\frac{3}{10} \\
\end{array}
\right)$
