### Instruction:
 Kabla ya kupoteza moja, Askari O'Brien alikuwa na kofia 5 zaidi ya mara mbili ya kofia za Mkuu wa Zima Moto Simpson. Ikiwa Mkuu wa Zima Moto Simpson ana kofia 15, Askari O'Brien ana kofia ngapi sasa?


### Response:
 Tuiteni idadi ya kofia ambazo Askari O'Brien ana kama x.
Kisha x - 5 = 2(15), au x - 5 = 30, hivyo x = 30 + 5 = <<30+5=35>>35.
