Answer:
Number of doubles games = 6
Number of singles games = 7
Step-by-step explanation:
Let the number doubles be d and number of singles be s.
There are 13 matches in progress.
d + s = 13 ----------------------eqn 1
There are 38 people playing tennis. A doubles match requires 4 players, and a singles match requires 2 players.
4 d + 2 s = 38 ----------------------eqn 2
eqn 1 x 2
2d + 2s = 26 ----------------------eqn 3
eqn 2 - eqn 3
4 d + 2 s - 2d + 2s = 38 - 26
2d = 12
d = 6
Substituting in eqn 1
6 + s = 13
s = 7
Number of doubles games = 6
Number of singles games = 7
