Let the number of games Ahmadullah's basketball team played last season be represented by \( x \).
According to the problem, this season they will play 21 games, which is 12 games more than the number of games they played last season. We can set up the equation:
\[ 21 = x + 12 \]
To find \( x \), we can subtract 12 from both sides:
\[ x = 21 - 12 \] \[ x = 9 \]
So, the number of games they played last season was 9 games. However, it looks like 9 games isn't one of the options listed.
Given the options:
- 27 games
- 7 games
- 33 games
- 11 games
None of those match the calculated value of 9 games.
Please double-check the problem's parameters or options given, as there seems to be an inconsistency.
