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

### Instruction:
 Rodney, Roger na Ron wanaweza kubeba uzito jumla wa pauni 239. Rodney anaweza kubeba mara mbili ya uzito wa Roger, na Roger anaweza kubeba pauni 7 chini ya mara nne ya uzito ambao Ron anaweza kubeba. Rodney anaweza kubeba uzito kiasi gani?


### Response:
 Hebu x iwakilishe uzito ambao Ron anaweza kubeba.
Roger: 4x-7
Rodney: 2(4x-7)=8x-14
Jumla: x+4x-7+8x-14=239
13x-21=239
13x=260
x=<<20=20>>20
Rodney: 8(20)-14=146 pauni
