Please provide all steps to solving the ODE. Please explain how to solve each ODE (rules, identities). How do you tell the order of the ode?

Solve the ODEs below using the method of separation of variables; use variable substitut tions if appropriate, including problems without a suggested substitution. (a) y' = y(3 - y) y ( b) y = suggested substitution: u = y/x x+ xy (c) y = x- y (d) y' = (x-y-2)2 2xy (e) y' = 2 2 - y2
