Find dy.
xy^4 + x ^ 2 y = x + 3y
xy4+x2y=x+3yDifferentiating implicitly, we have thaty4+4xy3dydx+2xy+x2dydx=1+3dydxCollecting like terms, we have thatdydx(4xy3+x2−3)=1−2xy−y4 ⟹ dydx=1−2xy−y44xy3+x2−3xy^4 +x^2y = x +3y\\ \text{Differentiating implicitly, we have that}\\ y^4 + 4xy^3\frac{dy}{dx} +2xy + x^2 \frac{dy}{dx}= 1 +3\frac{dy}{dx}\\ \text{Collecting like terms, we have that}\\ \frac{dy}{dx}(4xy^3+x^2-3)= 1-2xy-y^4\\ \implies \frac{dy}{dx} = \frac{1-2xy-y^4}{4xy^3+x^2-3}xy4+x2y=x+3yDifferentiating implicitly, we have thaty4+4xy3dxdy+2xy+x2dxdy=1+3dxdyCollecting like terms, we have thatdxdy(4xy3+x2−3)=1−2xy−y4⟹dxdy=4xy3+x2−31−2xy−y4
