Answer:

This is an Ordinary, First Order, Separable Differential Equation and its solution will be as follows: * By Separating the variables, gives: dY / Y+1 = dX /X+3 * Then, by integration for both sides, gives : ln ( Y + 1 ) = ln ( X + 3 ) + C (where C is an arbitrary constant) *Finally, by further simplification, gives: ln [( Y+ 1 ) / ( X + 3 )] = C [( Y + 1 ) / ( X + 3 )] = exp(C) Y = [X*exp(C)] + [3*exp(C)] - 1
