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

### Instruction:
 Brittany ana panya 3: Puffy, Muffy, na Scruffy. Puffy anapima uzito wa unga 5 zaidi ya Muffy. Muffy anapima uzito wa unga 3 chini ya Scruffy. Ikiwa Scruffy anapima uzito wa unga 12, vipi uzani ungeonyeshwa, kwa unga, ikiwa Brittany angepima Puffy na Muffy kwenye mizani?


### Response:
 Ikiwa Scruffy anapima uzito wa unga 12, na Muffy anapima uzito wa unga 3 chini ya Scruffy, basi Muffy anapima uzito wa unga 12 - 3 = <<12-3=9>>9.
Ikiwa Puffy anapima uzito wa unga 5 zaidi ya Muffy, basi Puffy anapima uzito wa unga 9 + 5 = <<9+5=14>>14.
Ikiwa Brittany anapima Puffy na Muffy, mizani itaonyesha unga wa 9 + 14 = <<9+14=23>>23.
