We can identify that the differential equation $\frac{dy}{dx}=\frac{y-x}{x}$ 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

Learn how to solve differential equations problems step by step online. Solve the differential equation dy/dx=(y-x)/x. We can identify that the differential equation \frac{dy}{dx}=\frac{y-x}{x} 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. Integrate both sides of the differential equation, the left side with respect to y, and the right side with respect to x.

Final answer to the problem

$y=\left(-\ln\left(x\right)+C_0\right)x$
