Consider the system of differential equations dx/dt=−2y dy/dt=−2x. . Convert this system to a second order differential equation in yy by differentiating the second equation with respect to tt and substituting for xx from the first equation. Solve the equation you obtained for y as a function of t; hence find x as a function of t. If we also require x(0)=4 y(0)=3, what are x and y?x(t)= y(t)=
