Solving for the Number of Girls Playing Volleyball

To solve for the number of girls playing volleyball, let's denote the number of girls as x. Given that there were 11 boys and an equal number of players on each team, we can set up the following equation:

11 + x = 2 * 9

Now, let's solve for x:

11 + x = 18 x = 18 - 11 x = 7

So, there were 7 girls playing volleyball.

Equation:

11 + x = 2 * 9

Solution:

x = 7
