Question
Solve the following system of differential equations (in the picture below)
![The image shows a system of differential equations:
\[
\begin{cases}
\frac{dx}{dt} = 2x - 5y, \\
\frac{dy}{dt} = x - 2y + \cos t
\end{cases}
\]
This system consists of two equations involving derivatives with respect to time \( t \). The first equation, \(\frac{dx}{dt} = 2x - 5y\), describes how the variable \( x \) changes over time as a function of both \( x \) and \( y \). The second equation, \(\frac{dy}{dt} = x - 2y + \cos t\), describes how the variable \( y \) changes over time, influenced by \( x \), \( y \), and the cosine of \( t \). This system can be used to model dynamic systems where interactions between variables \( x \) and \( y \) are influenced by an oscillating factor \(\cos t\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F40884399-19a4-4ad9-a712-30c31bac2ede%2F80fa5438-382c-4bbd-8b95-c18dda3a68cd%2F255dp38_processed.png&w=3840&q=75)
