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

### Instruction:
Merill has twice as many marbles as Elliot and the two of them together have five fewer marbles than Selma. If Selma has fifty marbles, how many marbles does Merill have?

### Response:
 Ikiwa Selma ana mabulingo hamsini, basi Merill na Elliot pamoja wana mabulingo 50-5 = <<50-5=45>>45.
Tutachukulia Elliot ana mabulingo x.
Ikiwa Merill ana mara mbili ya mabulingo ya Elliot, basi jumla ya mabulingo wanayomiliki pamoja ni 2x+x = 45.
Hii inabadilika kuwa 3x=45.
Idadi ya mabulingo ambayo Elliot anamiliki ni x=45/3.
Hii inamaanisha Elliot ana mabulingo x=<<15=15>>15.
Kwa kuwa Merill ana mara mbili ya mabulingo ya Elliot, Merill ana mabulingo 2*15 = 30.
