To find out how many games Ahmadullah's basketball team played last season, we can set up the equation based on the information given:
Let \( x \) be the number of games played last season.
According to the problem, this season they are playing 21 games, which is 12 games more than what they played last season. We can express this relationship with the following equation:
\[ 21 = x + 12 \]
Now, we can solve for \( x \) by subtracting 12 from both sides:
\[ 21 - 12 = x \] \[ x = 9 \]
So, Ahmadullah's basketball team played 9 games last season. However, this option is not listed in your choices.
Please double-check the context or the numbers in the problem; the provided response options (33, 11, 7, and 27 games) do not match the calculation.
