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

### Instruction:
A particular train has some passenger cars and a number of cargo cars equal to half the number of passenger cars plus three. If the total number of cars is 71, counting the engine and caboose, how many passenger cars are in the train?

### Response:
 Kwanza tafuta idadi ya magari bila kuhesabu injini na gari la mwisho: magari 71 - magari 2 = <<71-2=69>>69 magari
Acha p iwe idadi ya magari ya abiria na c iwe idadi ya magari ya mizigo. Tunajua kwamba p + c = 69 na c = p/2 + 3.
Kwa kubadilisha equation ya pili katika equation ya kwanza, tunapata p + p/2 + 3 = 69
Kwa kuunganisha vipengele sawa, tunapata 1.5p + 3 = 69
Kwa kutoa 3 kutoka pande zote mbili, tunapata 1.5p = 66
Kwa kugawanya pande zote mbili na 1.5, tunapata p = 44
