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

### Instruction:
 Barry anataka kutengeneza saladi kubwa kwa kutumia matango na nyanya tu. Atatumia jumla ya vipande 280 vya mboga. Ikiwa kuna nyanya mara tatu zaidi ya matango, matango mangapi yatatumiwa katika saladi?


### Response:
 Hebu c iwe idadi ya matango na t iwe idadi ya nyanya. Tunajua kwamba c + t = vipande 280 na t = 3c.
Kwa kubadilisha equation ya pili katika equation ya kwanza, tunapata c + 3c = vipande 280.
Kwa kuchanganya vipengele kama, tunapata 4c = vipande 280.
Kwa kugawanya pande zote na 4, tunapata c = vipande 70.
