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

### Instruction:
Bill and Jean are both cleaning out their garages. Bill makes a certain number of trips to the dump and Jean makes that many trips plus 6. If they make 40 trips total, how many trips does Jean make?

### Response:
 Hebu b iwe idadi ya safari ambazo Bill anafanya na j iwe idadi ambazo Jean anafanya. Tunajua kwamba b + j = 40, na j = b + 6.
Kwa kubadilisha equation ya kwanza katika equation ya pili, tunapata b + b + 6 = 40
Kwa kuunganisha vipengele kama, tunapata 2b + 6 = 40
Kwa kutoa 6 kwa pande zote, tunapata 2b = 34
Kwa kugawanya pande zote na 2, tunapata b = 17
Kwa kubadilisha thamani hiyo katika j = b + 6, tunapata j = 17 + 6 = <<23=23>>23
