Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
 Pamoja, marafiki 3 walitazama video fupi 411. Kelsey alitazama video 43 zaidi ya Ekon. Ekon alitazama video 17 chini ya Uma. Kelsey alitazama video ngapi?


### Response:
 Hebu U = idadi ya video ambazo Uma alitazama
Ekon = U - 17
Kelsey = (U - 17) + 43 = U + <<(-17)+43=26>>26
U + U - 17 + U + 26 = 411
3U + 9 = 411
3U = 402
U = <<134=134>>134
Kelsey = 134 + 26 = <<134+26=160>>160 video
Kelsey alitazama video 160.
