Question 1072384

In a soccer tournament the winning team gets 3 points, the losing team gets 0 points, and in a tie both teams get 1 point each. My team played 31 games and received 64 points. 7 of the games were ties. How many games did my team lose?

Thank you
<pre>The team lost: {{{highlight_green(matrix(1,2, 5, games))}}}
Can you figure out how I derived that?
