To find out how many games Ahmadullah's basketball team played last season, we can set up an equation based on the information provided.
Let \( x \) represent the number of games played last season.
According to the problem, this season they will play 21 games, which is 12 games more than last season's games. We can express this relationship with the following equation:
\[ 21 = x + 12 \]
Now, solving for \( x \):
\[ x = 21 - 12 \]
\[ x = 9 \]
So, the team played 9 games last season. However, this option is not among the choices provided.
To check the calculations:
If they played 9 games last season, then:
9 (last season) + 12 (more games this season) equals 21 games this season, which is correct.
Since none of the provided options (7, 11, 27, 33) match our result, we conclude that the choices presented do not include the correct answer which is 9 games.
