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

### Instruction:
 Martha ana matofaa 20. Ameamua kuyagawa kwa marafiki zake. Jane alipata matofaa 5 kutoka kwake, na James alipata 2 zaidi ya Jane. Martha anahitaji kutoa matofaa mangapi zaidi ili abaki na matofaa 4 tu?


### Response:
 James alipata matofaa 5 + 2 = <<5+2=7>>7.
Kwa hivyo Martha alitoa matofaa 5 + 7 = <<5+7=12>>12.
Hiyo itamwacha na matofaa 20 - 12 = <<20-12=8>>8.
Kwa hivyo Martha anahitaji kutoa matofaa 8 - 4 = <<8-4=4>>4 zaidi ili abaki na 4 tu.
