a student playing a computer chess game gets 5 points every time he wins a round.the computer gets 3 points every time it wins a round.they play 64 rounds and end with a tied score.how many rounds did the computer win.
please help me ..
i think the answer is 8 because...
5+3=8
64/8=8
3*8=24
5*8=40
40+24=64
i don't know if that's the answer

let the number of your wins be x
then the number of computer wins is 64x
5x = 3(64x)
5x = 192  3x
8x = 192
x = 24
students wins 24 games, computer wins 40 games
test:
5x24 = 120
3x40 = 120
