Solve the following real-world problem: Ahmadullah’s basketball team will play 21 games this season. That is 12 games more than 1/3 the number of games they played last season. How many games did they play last season?
Let's denote the number of games Ahmadullah's basketball team played last season as "x".
According to the problem, the number of games they will play this season is 12 games more than 1/3 of the number of games they played last season.
So, we can set up the equation:
x/3 + 12 = 21
To isolate x, we need to subtract 12 from both sides of the equation:
x/3 = 21 - 12
x/3 = 9
To solve for x, we multiply both sides of the equation by 3:
3(x/3) = 3(9)
x = 27
Therefore, Ahmadullah's basketball team played 27 games last season.
