Annette's soccer team will play 15 games this season. That is 7 games fewer than 2 times the number of games they played last season. How many games did they play last season? Which equation represents this problem?

Question

A. 15 - 7 = 2x
B. 7 - 2x = 15
C. 2x - 7 = 15
D. 2x + 7 = 15

Answer 1

Let x represent the number of games they played last season.

According to the problem:
15 = 2x - 7
15 + 7 = 2x
22 = 2x
x = 11

Therefore, they played 11 games last season.

The equation that represents this problem is:
C. 2x - 7 = 15
