Answer 3

OK lets start out simple

Answer 4

HR = Horse and HM= Human

Answer 5

ok?

Answer 6

Okay.

Answer 7

So HM + HR =?

Answer 8

74

Answer 9

Yup!

Answer 10

So 2HM + 4HR =?

Answer 11

196?

Answer 12

Correct!

Answer 13

So (2HM + 4HR) - (2 HM + 2HR) =?

Answer 14

Okay, give me a minute.

Answer 15

Yup! take all the time you need :)

Answer 16

I'm not so sure here. :/

Answer 17

What its saying is 196 - 148=?

Answer 18

48

Answer 19

Yup!

Answer 20

So 2HR = 48 and HR = 24

Answer 21

h + p=74
4h + 2p=196 (horses have 4 legs people have 2)

p=74 - h

4h + 2(74 - h)=196 (plug (74 - h) in for p, then solve)
4h + 148 - 2h=196
2h=48
h=24 (which means p=50)

There are 24 horses and 50 humans!

Answer 22

So HM + (24) =?
