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

### Instruction:
 Jana, kituo cha wanyama kilichofunguliwa hivi karibuni kilipokea wanyama wao wa kwanza 60. Walipata paka 20 zaidi ya mbwa. Waliwachukua paka wangapi?


### Response:
 Hebu x iwe idadi ya mbwa.
Walichukua paka 20+x.
Jumla ya wanyama ni x+(20+x)=60
2x+20=60
2x=40
x=<<20=20>>20
Walikuwa na paka 20+20=<<20+20=40>>40.
