### Problem Statement

2. Find all values of \( x \) and \( y \) such that:

\[
f_x(x, y) = 0 \quad \text{and} \quad f_y(x, y) = 0
\]

simultaneously.

### Function Definition

The function is given by:

\[
f(x, y) = 5x^3 - 11xy + y^3
\]

### Solution Condition

The solution should be expressed as:

\[
(x, y) = (\text{larger } x\text{-value})
\]

### Notes

To solve this problem, you will need to find the partial derivatives \( f_x(x, y) \) and \( f_y(x, y) \), set them equal to zero, and solve the resulting system of equations to find the critical points. The critical points are where these conditions are met.
