?

2. 1234portion

before we continue what are your credentials?? if you dont mind me asking

Let A be number of humans, B be number of horses human has 2 legs, horse has 4 legs A+B = 74 2A+4B = 196 solve system using substitution or elimination ... credentials? college degree in math

4. 1234portion

so to be clear how man humans and how many horses?

5. dumbcow

you have to solve system of 2 equations with 2 unknowns Multiply top equation by -2, then add the equation to eliminate variable A -2A -2B = -148 2A + 4B = 196 ----------------- 2B = 48 Solve this for B, then substitute back in to find A can you take it from here?

id like you to continue ma'am/or sir!

7. dumbcow

B = 48/2 B = 24 A+B = 74 A+24 = 74 A = 74-24 = 50 There are 50 humans and 24 horses

9. 1234portion

in your honest opinion was this question hard for you?

10. dumbcow

sounds like you are taking a survey or something? do you really need help in math?? no this was not hard for me, but im here to help not ask questions
