Problem

For the curve exy+x2y=7e^{xy}+x^{2}y=7, determine dxdy\dfrac{dx}{dy} in terms of xx and yy.
Intuitive explanation

This problem asks you to find the rate of change of xx with respect to yy — which is the reciprocal perspective on implicit differentiation. Instead of the usual dydx\frac{dy}{dx}, you're treating yy as the independent variable. Differentiate both sides with respect to yy (remembering that xx is now the dependent variable), apply the product and chain rules carefully, then solve for dxdy\frac{dx}{dy} algebraically.
