Please help me solve these intitial value questions. I need help finding the answer as a formula of y. Thank You!

a). (dy/dx) = xy / (x+4) , where y(-3)=2 . (assume that x>(-4) to simplify any absolute values that may occur)

b). (dy/dt) = 2y/t , where y(3)=4

c). y' = 2*e^(2x-y) , where y(0) = ln(3). Please help me find an exact formula for y=y(x)

Let me know if there is anything I need to elaborate on / didn't explain properly. Thank you!!
