Math is the language of science, not a science in itself.

Discuss.

Dear /sci/,
I am doing differential equations homework, and I have hit a wall.

It is asking if this equation:
e^(xy) + y = x - 1
is the implicit solution to
dy/dx = (e^(-xy) - y) / (e^(-xy) + x)


It claims in the back the answer is yes. I have no fucking clue how they got to this at all. I get something like this when I implicitly differentiate:

dy/dx = (1 - xyy' * e^(xy)) / y

Any ideas? Did they just fuck up? Am I missing something?
