Solve each problem. To visualize the situation, use graph paper and a compass to carefully graph each circle.

The locations of three receiving stations and the distances to the epicenter of an earthquake are contained in the following three equations: (x - 2)² + (y - 1)² = 25, (x + 2)² + (y - 2)² = 16, and (x - 1)² + (y + 2)² = 9. Determine the location of the epicenter.
