= (((x + 11) * 6 - 3) / 3 + 5) / 2 - x = ((6x + 66 - 3) / 3 + 5) / 2 - x = ((6x + 63) / 3 + 5) / 2 - x = (2x + 21 + 5) / 2 - x = (2x + 26) / 2 - x = x + 13 - x = 13 finally geez
Ex 2 theres 16 teams. after a team that loses twice they're out. 1 should be left, therefor 15 teams should be out. 15 * 2 = 30, there should be 30 or 31 games if the last team alive lost 1 game.
