This is a problem in differential equations.

Find the operational determinant and solve the equation.

x'= 4x + y + 2t

y' = -2x + y

2. Relevant equations

3. The attempt at a solution

I'm at a total loss. All the examples in the book have problems with the form:

(D - 4)x + 3y = 0

-6x + (D + 7)y = 0

Nothing like what I have, and certainly nothing with x,y, AND t. That t really throws me off.
