Get a step-by-step solution for a system of linear differential equations?

[jenba1 (Jose Enriquez de la Barrera)]

I was trying to input this equation onto wolfram alpha, but it’s just giving me the result and not the step-by-step solution, how could i visualize it?

dx/dt=-3y+t, dy/dt=-3x-1 when x(0)=0 and y(0)=1
