You provided the equation \( y - x + xy\cot(x) + xy' = 0 \). Let's solve it for \( y' \) using differentiation techniques.

### Step-by-Step Solution:

1. Rearrange the equation to isolate the term containing \( y' \):
   \[
   xy' = - y + x - xy\cot(x)
   \]

2. Divide both sides by \( x \) to solve for \( y' \):
   \[
   y' = \frac{- y + x - xy\cot(x)}{x}
   \]

Thus, the solution for \( y' \) is:
\[
y' = \frac{x - y - xy\cot(x)}{x}
\]
