What would dy/dx of tan(xy) be using implicit differentiation be?

If 3x^2+2xy+y^2=2 then what is the value of y'(1)?

My steps so far:

6x+2xy'+2y+2yy'=0

3x+xy'+y+yy'=0

Yy'+xy'=-3x-y

Y'=(-3x-y)/(y+x)

Would it be possible to find this or would the answer not be defined due to the two variables?
