How do I find the derivative dy/dx of:

x+ y= 3xy

I think I use the Sum Rule for the LHS and the Product Rule for the RHS.  Where I am confused is how to treat the y on the LHS.  Do you change it to 3y and then solve the whole thing for y?, or do you keep dy/dx*y and then solve the whole thing for dy/dx?

Any thoughts?
