Final answer:
The displacement is 5m east.
Step-by-step explanation:
The displacement is the straight line distance and direction from the starting point to the final position. To calculate the displacement, we subtract the total distance traveled in the west direction from the total distance traveled in the east direction. In this case, you walked 4m east, 2m west, and 3m east. So, the displacement would be 4m - 2m + 3m = 5m east.
