One day a person went to a hourse racing area,instead of counting the humans and the horses he instead counted the heads and leg there where 74 heads and 196 legs yet he still knew the number of the humans and the hourses.How did he figure that out and how many hourses and humans are there?
well let me check
24 hourses
50 humans
h = horses
p = people
h+p=74
4h + 2p = 196
h = 74-p
4(74-p) + 2p = 196
296 - 4p + 2p = 196
100 = 2p
50 = p
So ... yes. 50 humans. 24 horses. Good job.
