10. (3 points) The school has a total of 20 soccer balls and basketballs, which can accommodate 96 students playing at the same time. Each soccer ball is shared by 6 students, and each basketball is shared by 3 students. Among them, there are $\qquad$ soccer balls.
【Solution】Solution: Assume all are soccer balls,
$$
96 \div 6=16 \text { (units), } 4 \times 6=24 \text { (people), }
$$

Basketballs: $24 \div(6-3)$,
$$
\begin{array}{l}
=24 \div 3, \\
=8 \text { (units); }
\end{array}
$$

Soccer balls: $20-8=12$ (units);
Answer: There are 12 soccer balls.
Therefore, the answer is: 12.
