$\frac{dy}{dx}=\frac{x-y}{x+y}$
Learn how to solve problems step by step online. Solve the differential equation (x+y)dy/dx=x-y. Rewrite the differential equation. We can identify that the differential equation \frac{dy}{dx}=\frac{x-y}{x+y} is homogeneous, since it is written in the standard form \frac{dy}{dx}=\frac{M(x,y)}{N(x,y)}, where M(x,y) and N(x,y) are the partial derivatives of a two-variable function f(x,y) and both are homogeneous functions of the same degree. Use the substitution: y=ux. Expand and simplify.
