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

### Instruction:
The sum of the ages of three boys is 29. If two of the boys are the same age and the third boy is 11 years old, how old are the other two boys?

### Response:
 Mvulana wa tatu ana umri wa miaka 11 kwa hivyo jumla ya umri wa wavulana wawili wa kwanza ni 29-11 = 18
Umri wa wavulana wawili wa kwanza ni sawa kwa hivyo kila mmoja wao ana umri wa 18/2 = <<18/2=9>>9 miaka
