Determine whether the given relation is an implicit solution to the given differential equation. Assume that the relationship does define y implicitly as a function of x and use implicit differentiation. -xy -y dy e +y=x+3, dx -wy+X -xy- dy V equivalent to dx Va solution to the differential equation. Therefore, e+ yx+3 y+x Applying implicit differentiation to the equation gives which
