# Solve the differential equation$y\;e^{\large\frac{x}{y}}\;dx=\bigg(x\;e^{\Large\frac{x}{y}}+y^2\bigg)dy\;(y\neq0)$

Toolbox:
• If the linear differential equation is of the form $\large\frac{dx}{dy}$$= F(x,y), is said to be homogenous if F(x,y) is a homogenous function of degree 0. • This type of equation can be solved by substituting x= vy and \large\frac{dx}{dy} =$$ v+y\large\frac{dv}{dy}$
Step 1:
Given :$y\;e^{\large\frac{x}{y}}\;dx=\bigg(x\;e^\frac{x}{y}+y^2\bigg)dy$
we can write the equation as $\large\frac{dx}{dy} = \frac{[xe^{\Large(x/y)} +y^2]}{y.e^{\Large(x/y)} }$
Using the information in the tool box, we understand this given equation is a homogenous function of dergree 0,
