Q1) Solve the following differential equation by using integrating factors. Assume x>0 FOR Q1

x y' = 3y+x^2

Solve the following differential equation by using integrating factors.

Q2) x y' = 7y-4x^2

Q3) y' = y+e^(7x)

Q4) y' = 5y+xe^x , y(0) = 5

Q5)(1+x^2) y' = y-4 , y (0) = 3

Q6) y' = y+3x^2 , y (0) = 9

Thank you for your help :)
