\begin{enumerate}
\item Find the solution of the differential equation at time $t = 10$
\begin{align*}
\dot{x}_1 &= -x_1 + 3 x_2 + 2\\
\dot{x}_2 &= -2 x_2 + 1
\end{align*}
Consider the initial condition be $(0.1,0.2)$ at $t = 0$.
\item Plot the solution of the above differential $(x_1,x_2)$ for $t \in [0.2,10]$.
\end{enumerate}
{\bf Solution:}
