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

### Instruction:
 Ali, Peter, na Joey walikuwa wanavua samaki. Samaki Ali aliyevua ulikuwa na uzito mara mbili ya samaki aliyevua Peter. Joey alivua samaki mmoja zaidi ya Peter. Pamoja, wote watatu walivua samaki wenye uzito wa kilogramu 25. Ali alivua samaki wangapi?


### Response:
 Hebu tuchukue x kuwa uzito wa samaki aliyevua Peter.
Kisha Ali na Joey walivua samaki wenye uzito wa 2*x na x+1 kg, mtawalia.
x+ 2*x + x+1 = 4*x + 1 = 25
4*x = 24
x = <<6=6>>6
Ali alivua 2*x = 2*6 = <<2*6=12>>12 kg za samaki.
