The Attempt at a Solution
So First I checked if both equations were exact. I took the derivative of 3xy^2+4y and also derivative of the other and they were both equal so the equation is exact.
I took the 3xy^2+4y and integrated it with respect to x. And then I differentiated it to y.
I got 3x^2y+4x out of it. The problem is that it is exactly the same as the one from the originally equation so I did not ending up finding C.
Did I do something wrong?
