solve the following system of linear non-homogeneous differential equations with eigenvalues/eigenvectors and variation of parameters

The image presents a system of differential equations in matrix form. It is expressed as follows:

\[ 
\frac{d\mathbf{z}}{d\mathbf{t}} = \begin{bmatrix} 0 & 2 \\ -1 & 3 \end{bmatrix} \mathbf{z} + \begin{bmatrix} 2 \\ e^{-3t} \end{bmatrix} 
\]

where 

\[
\frac{d\mathbf{z}}{d\mathbf{t}} = \begin{bmatrix} z_1' \\ z_2' \end{bmatrix} 
\]

and 

\[
\mathbf{z} = \begin{bmatrix} z_1 \\ z_2 \end{bmatrix} 
\]

This system describes how the vector \(\mathbf{z}\), consisting of the components \(z_1\) and \(z_2\), evolves over time \(t\). The matrix on the right-hand side contains constant coefficients, determining how these components interact. The additional vector represents external input or forcing terms, with an exponential term \(e^{-3t}\) indicating a time-dependent influence.
