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

### Instruction:
Every room in a building has at least two windows and a maximum of 4 windows. There are 122 windows total. If 5 rooms have 4 windows and 8 rooms have 3 windows, how many rooms in the building have 2 windows?

### Response:
 Tunajua kuwa vyumba 5 vina madirisha manne, hivyo madirisha 20 kwa sababu 4*5=20
Pia tunajua kuwa vyumba 8 vina madirisha matatu, hivyo madirisha 24 kwa sababu 8*3=24
Hadi sasa, tumehesabu madirisha 44 kwa sababu 20+24=<<20+24=44>>44
Kuna madirisha 78 yaliyobaki kwa sababu 122-44 = <<122-44=78>>78
Kwa hivyo, kuna vyumba 39 vyenye madirisha mawili kwa sababu 78/2 =<<78/2=39>>39
