Let the number of games Ahmadullah's team played last season be \( x \).
According to the problem, the team will play 21 games this season, and that is 12 games more than last season's games. We can write the equation:
\[ 21 = x + 12 \]
Now, we can solve for \( x \):
\[ x = 21 - 12 \] \[ x = 9 \]
The number of games they played last season is 9 games. However, this option is not provided in the responses given.
So, given the answer choices you provided (33, 11, 7, 27), none of them are correct according to the calculations. If the intention is to find the closest possible answer or verify the problem set up, please provide more context or check for any errors.
