Solve the following real-world problem: Ahmadullah's basketball team will play 21 games this season.  That is 12 more games than  1/3

 the number of games they played last season. How many games did they play last season?

Let x be the number of games Ahmadullah's basketball team played last season.

The number of games they will play this season is 1/3 * x + 12 games.
We know that 1/3 * x + 12 = 21 games.
Subtracting 12 from both sides, we get 1/3 * x = 9.
Multiplying both sides by 3, we get x = 27.
Therefore, Ahmadullah's basketball team played 27 games last season. Answer: \boxed{27}.

To find out how many games Ahmadullah's basketball team played last season, we can use the information given in the problem.

Let's assume the number of games they played last season is represented by the variable x.

According to the problem, the team will play 21 games this season, which is 12 more games than 1/3 the number of games they played last season.

So, we can set up an equation to represent this information:

21 = (1/3)x + 12

To solve this equation, we need to isolate x by subtracting 12 from both sides:

21 - 12 = (1/3)x

9 = (1/3)x

To get rid of the fraction, we can multiply both sides of the equation by 3:

(3 * 9) = (3 * (1/3)x)

27 = x

Therefore, Ahmadullah's basketball team played 27 games last season.

To solve this real-world problem, we need to first establish the information given and the unknown variable. Let's call the number of games they played last season "x".

According to the problem, Ahmadullah's basketball team will play 21 games this season, which is 12 more games than 1/3 of the number of games they played last season.

To calculate the number of games they played last season, we can set up an equation:

21 = (1/3)x + 12

To solve this equation, we need to isolate the variable x. We can do this by performing some algebraic operations. Let's solve the equation step by step:

1. Subtract 12 from both sides of the equation:
21 - 12 = (1/3)x

2. Simplify the left side of the equation:
9 = (1/3)x

3. Multiply both sides of the equation by 3 to eliminate the fraction:
3 * 9 = 3 * (1/3)x
27 = x

Therefore, the number of games they played last season (x) is 27.
