Answer 2

well horses have got 4 legs and human 2 but both have got 1 head

Answer 3

Answer 4

so u just need to set up 2 equations:
let x humans and y horses,
x+y=78 --->(1)
2x+4y=196---->(2)
now solve these,can u ?

Answer 5

no:(

Answer 6

2x+2y=156
2x+4y=196
2y= 40
y=20

Answer 7

ok, from 2nd equation we have ,
x+2y= 98---->(3)
now do (3) - (1)

Answer 8

2

Answer 9

x+y=78...now y=20
x+20=78
x=78-20=58
