Let \( x \) represent the number of games Annette's soccer team played last season. According to the problem, the team will play 15 games this season, which is 7 games fewer than 2 times the number of games played last season. We can express this relationship with the following equation:
\[ 2x - 7 = 15 \]
So, the correct representation of the problem in the form \( px + q = r \) is:
2x − 7 = 15
