wouldn't you jut use implicit differentiation and then substitute?

ok first you find a diff of y=ln(x), and replace in the equation, is most easy, sorry i dont have a good english

\[dy = (x-10)dx*e^-(x)\] \[e^y*dy = (x-10)dx\]

I'm not sure I understand. In my answer I used partial derivatives, but I'm not sure how I got the answer when I did it previously...

fxx(x,y)=6x and fyy(x,y)=2 and fxy(x,y)=-6, and I got D=6x(2)-(-6)^2=12x-36 which is the answer... but I don't know where I got 6x(2)-(-6)^2 from previously.
