My ans is (y(-16-3x^2y))/ x(96+7x^2y) but at wolfram is y^6(3x^2y+16). Btw i use product rule to dy/dx.

Need someone to recheck my ans.

**Steve**, Sunday, October 28, 2012 at 1:08am3x^2y^7 + 7x^3y^6y' + 16y^6 + 96xy^5 y' = 0

y'(7x^3y^6+96xy^5) = -(3x^2y^7 + 16y^6)

y' =

-y^6 (3x^2 y + 16)

---------------------

xy^5 (7x^2 y + 96)

y' =

-y(3x^2y+16)

-----------------

x(7x^2 y + 96)

you are correct, and Wolfram agrees for me. If the answer you got was different, you must have mistyped it into Wolfram
