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

### Instruction:
Barbeck has two times as many guitars as Steve, but Davey has three times as many guitars as Barbeck. If there are 27 guitars altogether, how many guitars does Davey have?

### Response:
 Hebu x iwe idadi ya gitaa Steve anayo.
Barbeck ana gitaa 2x, na Davey ana gitaa 3 * 2x = 6x.
2x + 6x + x = 27
9x = 27
x = 27 / 9 = <<27/9=3>>3 hivyo Steve ana gitaa 3
Barbeck ana gitaa 2 * 3 = <<2*3=6>>6
Na Davey ana gitaa 3 * 6 = <<6*3=18>>18
