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

### Instruction:
Albert noticed a flock of geese flying together in a V formation in the sky overhead.  One half of the geese broke off from the formation, flew toward the earth, and landed in some trees.  Then, 4 geese flew up, out of the trees, and joined those already flying in the air to make a new V formation in the sky.  If the final number of geese flying in the V formation was 12, how many geese were in the first formation Albert noticed in the sky?

### Response:
 Ikiwa idadi ya mwisho ya bata ilikuwa 12, ambayo ilijumuisha bata 4 waliojiunga kutoka mitini, basi kabla ya bata hawa 4 kujiunga, kulikuwa na bata 12-4=<<12-4=8>>8 angani.
Kwa kuwa hawa bata 8 wanawakilisha nusu ya bata waliobaki, basi umbo la awali lilikuwa na bata 8*2=<<8*2=16>>16.
