Find the general solution of the differential equations:`(x+y)(dx)/(dy)=1`

Explanation

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

### Step 1: Rewrite the equation
First, we can rewrite the given equation in a more standard form. We start with:
\[ (x+y) \frac{dx}{dy} = 1 \]
Dividing both sides by \(x+y\), we get:
...
