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

### Instruction:
A family has three adults and children, both girls and boys. They went out for a family trip and prepared 3 dozen boiled eggs for the trip. Every adult got 3 eggs, and the boys each received 1 more egg than each girl since the girls had some snacks. How many boys went on the trip if the number of girls was 7 and each girl received an egg?

### Response:
 Jumla ya mayai ambayo familia ilikuwa nayo ni 3 * 12 = <<3*12=36>>36 mayai
Kama kila mtu mzima alipokea mayai 3, jumla ya mayai waliyopata ni 3 * 3 = <<3*3=9>>9 mayai.
Watoto waligawana mayai 36 - 9 = <<36-9=27>>27
Kwa kuwa kila msichana alipokea yai, wavulana waligawana 27 - 7 = 20 mayai
Kama kila mvulana alipokea yai 1 zaidi kuliko kila msichana, kila mmoja alipokea 1+1 = <<1+1=2>>2 mayai
Wavulana waligawana 20 mayai, na kama kila mmoja alipokea 2 mayai, basi 20 mayai / 2 mayai/kijana = 10 wavulana walikwenda kwenye safari
