The equation $x = y$ implies that the variables $x$ and $y$ are equal. This means for any given value of $x$, $y$ will have the same value, and vice versa.

Examples:

1. If $x = 3$, then $y = 3$.
2. If $y = -5$, then $x = -5$.

This is a simple linear relationship where the graph of $x = y$ in a 2D Cartesian coordinate system is a straight line passing through the origin ($0, 0$) with a slope of 1.
