Hockey teams receive 2 points when they win and 1 point when they tie. One season, a team won a championship with 50 points. They won 10 more games then they tied. How many wins and how many ties did the team have.
Answer provided by our tutors
Let x : wins and y : ties
2x + y = 65
x = y + 10
Substitute : 2(y + 10) + y = 65
2y + 20 + y = 65
3y + 20 = 65
3y = 45
y = 15 so 15 ties
x = y + 10 so x = 25 wins
