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

### Instruction:
Compared to the amount of water she drank, Carla drank three times as much soda minus 6 ounces. If she drank 54 ounces of liquid total, how much water did she drink?

### Response:
 Hebu s iwe kiasi cha soda Carla alikunywa na w iwe kiasi cha maji alikunywa. Tunajua kwamba s + w = 54 na s = 3w - 6. Kwa kubadilisha equation ya pili katika equation ya kwanza, tunapata 3w - 6 + w = 54.
Kwa kuunganisha vipengele kama, tunapata 4w - 6 = 54.
Kwa kuongeza 5 kwa pande zote mbili, tunapata 4w = 60.
Kwa kugawanya pande zote mbili na 4, tunapata w = 15.
