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

### Instruction:
Adam has 50 balls. 20 balls are red, 10 are blue, and the rest are either pink or orange. If there are 3 times as many pink as orange balls, how many orange balls are there?

### Response:
 Kuna mipira 50-20-10 = <<50-20-10=20>>20 pinki na machungwa pamoja.
Ikiwa tunaruhusu x kuwa idadi ya jumla ya mipira ya machungwa, tunajua kuwa 3*x ni idadi ya mipira ya pinki.
Hivyo, 20=x+3*x=4*x
20=4x
x=<<5=5>>5
