Let's combine the like terms from the expression: 

\[
-y^2 - x - 3y^2 - xy
\]

### Step-by-step breakdown:

1. Combine the \(y^2\) terms: 
   \[
   -y^2 - 3y^2 = -4y^2
   \]

2. The \(x\) and \(xy\) terms are not like terms with \(y^2\), so they remain as they are:
   \[
   -x \quad \text{and} \quad -xy
   \]

Thus, the expression simplifies to:

\[
-4y^2 - x - xy
\]

This is the final simplified expression.
