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

### Instruction:
The cost of purchasing two commodities is $827. If the purchase price of the first one exceeds the other by $127, what is the purchase price of the first commodity?

### Response:
 Hebu X iwe bei ya bidhaa ya kwanza, hivyo bei ya bidhaa ya pili ni X - $127.
Gharama ya kununua hizo mbili ni X + (X - $127) = $827.
Kwa kuunganisha vipengele sawa, tunapata X*2 - $127 = $827.
Kwa kuongeza $127 kwa pande zote mbili, tunapata X*2 = $954.
Kwa kugawanya pande zote mbili kwa 2, tunapata X = $477.
