Designate w as the number of games won. The total of 25 must be the sum of the number of games won, the number lost, and the number tied. From the statement of the problem, the number of games lost must be 9 more than the number of games lost, or w + (w-9) equals number of games played minus number of games tied, or 2w - 9 = 25 - 2; 2w = 23 + 9 = 32; w = 16.
