For the following DEs, determine whether they are separable, linear, both, or

neither. I need to algebraically manipulate the DE to show it fits the form

of a separable or linear DE, or that it does not fit either of these forms. Not solving the problem.

(a): e^x y dy/dx = e^-y + e^(-2x-y)

(b): xdy = (xe^x -2y)dx

(c): y' + 3x^2 y = x^2
