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

### Instruction:
 Merill ana mara mbili ya mabulingo ya Elliot na wawili hao pamoja wana mabulingo matano chini ya Selma. Ikiwa Selma ana mabulingo hamsini, Merill ana mabulingo mangapi?


### 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.
