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

### Instruction:
 Reuben anaendesha duka la sandwich ambapo anauza sandwich yake ya jina lake na sandwich za pastrami. Pastrami inagharimu $2 zaidi ya Reuben. Anauza Reuben 10 na Pastrami 5 na anapata $55. Pastrami inagharimu kiasi gani?


### Response:
 Ikiwa X = "Bei ya Reuben" Tunajua kuwa 10(X) + 5(X+2) = 55
Hivyo 10X + 5X +10= 55
Hivyo, 15X = 45
Hivyo, bei ya Reuben ni $3 kwa sababu 45 / 15 =<<45/15=3>>3.
Kwa kuwa pastrami inagharimu $2 zaidi ya Reuben, bei ya pastrami ni $5 kwa sababu 3 + 2 = <<3+2=5>>5
