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

### Instruction:
Sally, Sam, and Steve went to play with their marbles. In the beginning, Sam has twice as many marbles as Steve while Sally has 5 less than Sam. After Sam has given Sally and Steve 3 marbles each, Sam has 8 marbles left. How many marbles does Steve have now?

### Response:
 Mwanzoni, Sam alikuwa na mabulinge mara mbili ya Steve, hivyo Steve alikuwa na mabulinge 1/2 ya Sam.
Sally alikuwa na mabulinge 5 chini ya Sam, hivyo Sally alikuwa na mabulinge 1/2 - 5 = <<1/2-5=-4.5>>-4.5 ya Sam.
Baada ya Sam kuwapa Sally na Steve mabulinge 3 kila mmoja, Sam alibakiwa na mabulinge 8.
Hivyo, Sam alikuwa na mabulinge 8 + 3*1/2 = <<8+3*1/2=9.5>>9.5.
Kwa kuwa Sally alikuwa na mabulinge -4.5, basi Steve alikuwa na mabulinge 4.5 - 3 = <<4.5-3=1.5>>1.5.
