Solve the following differential equation: `(1+e^(x//y))dx+e^(x//y)(1-x/y)dy=0`

Explanation

To solve the differential equation \( (1 + e^{\frac{x}{y}})dx + e^{\frac{x}{y}}(1 - \frac{x}{y})dy = 0 \), we will follow these steps:

### Step 1: Rewrite the equation
We start by rewriting the equation in the form:
\[ (1 + e^{\frac{x}{y}})dx + e^{\frac{x}{y}}(1 - \frac{x}{y})dy = 0 \]
This can be rearranged as:
