You can put this solution on YOUR website! Hi, there--
.
When you add together two vectors, you first add their horizontal displacements (5i+3i=8i). Then you add their vertical displacements (4j+(-4)j=0).
The sum of the two vectors is 8i+0j, or simply 8i.

Hope this helps! Feel free to email me if you have questions about this problem.
