1. 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? is it= 24 horses and 50 humans.
Yes. You can use the formula 196=4x+2y where x is the amount of horses and y is the amount of humans. So when you plug in 196=4(24)+2(50), the problem works.
