Pls help, I filled to understand on those Separable Differential equations and steps.

Find the function y = y(x) (for a > 0) which satisfies the separable differential equation dy 9+ 20x dx with the initial condition y(1) = 3.Solve the separable differential equation for u du e 5u+ 2t dt Use the following initial condition: u(0) = 10.\f\f
