One day, a person went to horse racing area, Instead of counting the number of human and horses, he instead counted 74 heads and 196 legs. Yet he knew the number of humans and horses there. How did he do it, and how many humans and horses are there? Help please. :) Thanx.

x + y = 74 
2x + 4y = 196 
(2x + 4y) - (2x+ 2y) = 196 - 148 
2y = 48 
y = 24 
x + (24) = 74 
x = 74 - 24 
x = 50


x = Humans
y = Horses

cwrw238 · Answer

let number of humans = x and number of horses

now humans and horses each have only one head ( as if you didnt know!!)

so 

x + y = 74

and also

2x + 4y = 196

solve these 2 equations simultaneously and you have your answer
