Help! Extremly hard Question!

OpenStudy (anonymous):

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?

hero (hero):

Not Hard...

OpenStudy (anonymous):

then why dont you solve it @Hero

hero (hero):

It's not that difficult

OpenStudy (lncognlto):

let horses = x and humans = y. therefore x + y = 74 horses have 4 legs and humans 2, so 4x + 2y = 196. Then solve by elimination/substitution

hero (hero):

Don't worry. Someone will help.

I want to assume that HM = Human and HR = Horse HM + HR = 74 2HM + 4HR = 196 like that right?

OpenStudy (lncognlto):

Yip, thats correct

OpenStudy (anonymous):

then after that, you do (2HM + 4HR) - (2 HM + 2HR) = 196 - 148 2HR = 48 HR = 24 HM + (24) = 74 HM = 74 - 24 HM = 50 correct right?

OpenStudy (lncognlto):

Yes, thats correct :)

Thank You for your help @lncognlto

OpenStudy (lncognlto):

You're welcome.

OpenStudy (anonymous):

x is nmber of humans and y is number of hourses than x+y=74 and x+4y=196 according to the condition now u can solve putting y=74-x in x+4y=196 and get ur answers
