The problem presents a linear system of differential equations:

\[
\begin{aligned}
x' &= 16x + 18y \\
y' &= -12x -14y
\end{aligned}
\]

with initial conditions:

\[
x(0) = 5, \quad y(0) = -3.
\]

### Steps to Solve:

1. **Matrix Representation**:
   The system can be written in matrix form as:
   \[
   \begin{pmatrix} x' \\ y' \end{pmatrix} = \begin{pmatrix} 16 & 18 \\ -12 & -14 \end{pmatrix} \begin{pmatrix} x \\ y \end{pmatrix}.
   \]

2. **Eigenvalue Problem**:
   We need to find the eigenvalues \(\lambda\) by solving the characteristic equation:
   \[
   \det \left( A - \lambda I \right) = 0,
   \]
   where \(A = \begin{pmatrix} 16 & 18 \\ -12 & -14 \end{pmatrix}\) is the coefficient matrix and \(I\) is the identity matrix.

3. **Solve the Characteristic Equation**:
   \[
   \det \begin{pmatrix} 16 - \lambda & 18 \\ -12 & -14 - \lambda \end{pmatrix} = 0.
   \]

   I'll calculate the eigenvalues next.The characteristic equation obtained is:

\[
\lambda^2 - 2\lambda - 8 = 0.
\]

Now, let's solve this quadratic equation to find the eigenvalues \(\lambda\).It seems like I can't do more advanced data analysis right now. Please try again later. If you'd like, I can guide you through solving the characteristic equation by hand or offer additional assistance on the theory behind the solution.
