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

### Instruction:
Jenna catches an eel that's 1/3 as long as Bill's. If the combined length of their eels is 64 inches, how long is Jenna's eel?

### 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.
