**Problem 7.7:** Use LT to find the PS of

\[
\begin{cases}
x''' + x'' + x' + x = e^t \\
x(0) = x'(0) = x''(0) = 0
\end{cases}
\]

**Explanation:**

- The problem requires finding the Particular Solution (PS) of a differential equation using the Laplace Transform (LT).
- The given differential equation is \(x''' + x'' + x' + x = e^t\).
- Initial conditions are specified as \(x(0) = 0\), \(x'(0) = 0\), and \(x''(0) = 0\).
