The problem provided is:

\[
\lim_{(x, y) \to (0, 0)} \frac{xy^2}{x^3 + 2y - 3x}
\]

### Solution:

To solve this limit as \((x, y) \to (0, 0)\), we'll check if the limit exists by trying different paths. If the limit yields different results along different paths, then the limit does not exist.

#### Path 1: Along \( y = 0 \)
When \( y = 0 \), the expression becomes:

\[
\frac{x(0)^2}{x^3 + 2(0) - 3x} = \frac{0}{x^3 - 3x} = 0
\]

Thus, along \( y = 0 \), the limit is \(0\).

#### Path 2: Along \( x = 0 \)
When \( x = 0 \), the expression becomes:

\[
\frac{0 \cdot y^2}{0^3 + 2y - 3(0)} = \frac{0}{2y} = 0
\]

Thus, along \( x = 0 \), the limit is also \(0\).

#### Path 3: Along \( y = x \)
Substitute \( y = x \) into the expression:

\[
\frac{x(x)^2}{x^3 + 2x - 3x} = \frac{x^3}{x^3 - x} = \frac{x^3}{x(x^2 - 1)} = \frac{x^2}{x^2 - 1}
\]

Now, as \( x \to 0 \):

\[
\frac{x^2}{x^2 - 1} = \frac{0}{-1} = 0
\]

So, along \( y = x \), the limit is also \(0\).

#### Conclusion:
Since the limit along the different paths gives the same result of \(0\), we can conclude that:

\[
\lim_{(x, y) \to (0, 0)} \frac{xy^2}{x^3 + 2y - 3x} = 0
\]
