Problem:
Add the two matrices
$\left(
\begin{array}{cc}
 -\frac{17}{3} & 3 \\
 -\frac{64}{9} & -\frac{76}{9} \\
\end{array}
\right)$ and
$\left(
\begin{array}{cc}
 9 & -\frac{58}{9} \\
 -\frac{5}{9} & \frac{19}{9} \\
\end{array}
\right)$
Answer:
$\left(
\begin{array}{cc}
 \frac{10}{3} & -\frac{31}{9} \\
 -\frac{23}{3} & -\frac{19}{3} \\
\end{array}
\right)$
