Question
**Title: Solving a Linear Differential System Using Elimination**

**Introduction:**
This section demonstrates how to use the elimination method to find a general solution for a given linear system with differentiation with respect to \( t \).

**Problem Statement:**
Solve the following linear system of differential equations:
\[
2x' + 10y = 0
\]
\[
x' - y' = 0
\]

**Instructions:**
Eliminate variable \( x \) and solve the resulting differential equation for \( y \). Select the correct solution from the options below.

**Choices:**

- **A.** \( y(t) = C_2 \sin(-5t) \)  
- **B.** \( y(t) = C_2 \cos(-5t) \)  
- **C.** \( y(t) = C_2 e^{5t} \)  
- **D.** \( y(t) = C_2 e^{-5t} \)  
- **E.** The system is degenerate.

**Conclusion:**
Apply the elimination method effectively to simplify the system and find the correct general solution for \( y(t) \). Evaluate the options given and identify the valid choice.
