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

### Instruction:
Before he lost one, Policeman O'Brien had 5 more than twice as many hats as fire chief Simpson. If fire chief Simpson has 15 hats, how many hats does Policeman O'Brien now have?

### Response:
 Tuiteni idadi ya kofia ambazo Askari O'Brien ana kama x.
Kisha x - 5 = 2(15), au x - 5 = 30, hivyo x = 30 + 5 = <<30+5=35>>35.
