![**Problem 7.5:** Find the GS of
\[
\begin{cases}
x + y' + z' = e^t \\
x' + y + z' = e^t \\
x' + y' + z = e^t
\end{cases}
\]
**Explanation:**
The problem presents a system of three first-order differential equations involving the functions \(x\), \(y\), and \(z\), and their derivatives \(x'\), \(y'\), and \(z'\). The right-hand side of each equation is the same term, \(e^t\).
The task is to find the general solution (GS) of this system of equations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F093e7116-3e01-49ad-9157-7a22a5caeb16%2F56048b44-32cc-4855-b432-80003912a7a6%2Fptkap9_processed.png&w=3840&q=75)
