Solution: Let: Win the x games, tying the (7-X) field.

3x + (7-X) = 17

X = 5

14-8 = 6 (field)

6 * (multiplied by) 3 = 18 (min)

18 +17 = 35 (minutes)

as it has been held in eight games, also lost a total of 7 games wins the peace games - so set wins X-games equaled the 7-X games 3X +7- X = 17 then the solution was X = 5 So, win 5 games 14 games to get the highest score after six games it is necessary to maintain the victory is equal to 6 × 3 = 18 points plus the original 17 so for 35 minutes
