Question
**Problem 1.** For each part below, write the linear system in matrix form.

(a)
\[
\begin{cases} 
\frac{dx}{dt} = 3x - 5y \\
\frac{dy}{dt} = 4x + 8y 
\end{cases}
\]

(b)
\[
\begin{cases} 
\frac{dx}{dt} = 3x - y + 2z + t - 1 \\
\frac{dy}{dt} = 2x - z - 3t^2 \\
\frac{dz}{dt} = -x + y + z + t^2 
\end{cases}
\]
