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

### Instruction:
Greg and Katie went to Mrs. Scarlet's gold store to have their gold chests opened. They realized Greg had four times less gold than Katie when Mrs. Scarlet opened the chests. If the total amount of gold is 100, how much gold does Greg have?

### Response:
 Tuseme Greg alikuwa na dhahabu x.
Katie alikuwa na 4*x = 4x
Jumla ya dhahabu walikuwa nayo ni dhahabu ya Katie 4x+x kwa Greg = 5x
Ikiwa Bi Scarlet alifungua masanduku na jumla ya dhahabu walikuwa nayo ni 100 = <<100=100>>100
Basi 5x = 100
Basi x = 100/5 = <<100/5=20>>20
Greg ana dhahabu x = 20
