Answer:
Scored 21 points
Step-by-step explanation:
John = x
Luke = l
Paul = p
x - 3 = l
2p = l
p + l + x = 39
Since Luke's score is twice of Paul's...
p + 2p + x = 39
Since John's score is 3 more than Luke..
p + 2p + p + 3 = 39
4p + 3 = 39
4p = 36
p = 9
2p = l
2(9) = 18
l = 18
18 + 3 = 21
21 + 18 = 39
