okay, we knew that a rabbit has 4 legs and a hen has 2 legs
call the number of rabbit x and number of hen y
4x+ 2y= 130
x+y =60
x = 60-y
4 (60-y) + 2y= 130
240- 4y +2y =130
240- 2y = 130
2y =110
y =55
x=5
so there are 55 hens and 5 rabbits

60=rabbits(two legs)
5=hens(two legs)
60×2=120
5×2=10
120+10=130 legs
60=rabbits(two legs)
5=hens(two legs)
60×2=120
