...but you know how to take the laplace of these expressions, right?

transform both DEs\[s^{2} X(s)  sx(0)  x'(0) = X(s) + 3Y(s)\]\[s^{2}Y(s)  sy(0)  y'(0) = 4X(s)\frac{4}{s1}\]plug in the initial conditions, simplify and solve for X(s) and Y(s)

It's easy if you already know how to do the laplace transform. You'll be left, as exraven explained, with two equations in two variables \(X(s)\) and \(Y(s)\), solve for them and then take the inverse laplace transform to each one separately.
