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

### Instruction:
Michael has two brothers. His oldest brother is 1 year older than twice Michael's age when Michael was a year younger. His younger brother is 5 years old, which is a third of the age of the older brother. What is their combined age?

### Response:
 Tuiteni x kuwa umri wa Michael.
Kaka mkubwa wa Michael ni x + 1.
Kaka mdogo wa Michael ni 5.
Kaka mkubwa ni mwaka mmoja mkubwa kuliko mara mbili ya umri wa Michael wakati Michael alikuwa mdogo kwa mwaka mmoja.
Hivyo, umri wa kaka mkubwa ni 2x + 2.
Kaka mdogo ni theluthi ya umri wa kaka mkubwa.
Hivyo, umri wa kaka mdogo ni 2x + 2 / 3.
Umri wao jumla ni x + 1 + 5 + 2x + 2 + 2x + 2 / 3.
Hivyo, umri wao jumla ni 3x + 10 + 2 / 3.
