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

### Instruction:
Antonio is a boy who eats a lot and his weight is 50 kilograms. Antonio's sister, who is an athlete, weighs 12 kilograms less than him. How much do the two siblings weigh together?

### Response:
 Uzito wa Antonio ni kilogramu 50. Dada yake ana uzito kilogramu 12 chini yake hivyo ana uzito wa kilogramu 50 - kilogramu 12 = <<50-12=38>>38 kilogramu.
Uzito wa wawili hao pamoja ni kilogramu 50 + kilogramu 38 = <<50+38=88>>88 kilogramu.
