Question
The vector function 

\[
\vec{x}(t) = \begin{bmatrix} e^{4t} \\ e^{4t} \\ e^{4t} \end{bmatrix}
\]

is a solution to the system of linear homogeneous differential equations:

\[
x_1' = 2x_1 + x_2 + x_3,
\]

\[
x_2' = x_1 + x_2 + 2x_3,
\]

\[
x_3' = x_1 + 2x_2 + x_3.
\]

**Exercises:**

1. Find the value of each term in the equation \(x_1' = 2x_1 + x_2 + x_3\) in terms of the variable \(t\). (Enter the terms in the order given.)

   \[
   \boxed{} = \boxed{} + \boxed{} + \boxed{} \quad \text{help (formulas)}
   \]

2. Find the value of each term in the equation \(x_2' = x_1 + x_2 + 2x_3\) in terms of the variable \(t\). (Enter the terms in the order given.)

   \[
   \boxed{} = \boxed{} + \boxed{} + \boxed{} \quad \text{help (formulas)}
   \]

3. Find the value of each term in the equation \(x_3' = x_1 + 2x_2 + x_3\) in terms of the variable \(t\). (Enter the terms in the order given.)

   \[
   \boxed{} = \boxed{} + \boxed{} + \boxed{} \quad \text{help (formulas)}
   \]
