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

### Instruction:
 Jenna anamkamata papa ambaye ni 1/3 ya urefu wa Bill. Ikiwa urefu wa papa zao ni jumla ya inchi 64, urefu wa papa wa Jenna ni upi?


### Response:
 Hebu j iwe urefu wa papa wa Jenna na b iwe urefu wa papa wa Bill. Tunajua kwamba b = 3j na b + j = 64.
Kwa kubadilisha equation ya kwanza katika equation ya pili, tunapata 3j + j = 64.
Kwa kuunganisha vipengee sawa, tunapata 4j = 64.
Kwa kugawanya pande zote mbili na 4, tunapata j = 16.
