1. The person moves 5 km west from the start.
2. Turning left (south) and moving 3 km.
3. Turning right (west) and moving 9 km.
4. Traveling north 3 km, returning to the original north level.
Total westward movement: \( 5 + 9 = 14 \) km.
Total northward movement cancels out the previous southward movement.
Thus, the person is 14 km west of the starting point.
