In equation let bear be x
, so x+x=120
so 2x=120
x=120/2
x=60
so the no of bear = 60
In equation 2
let rabbit be y
then y+60=70
so y= 70-60
hence y = 10
So the no of rabbit = 10
In equation 3
let the no. of fox be z
z+10+60=90
z+70=90
z=90-70
z=20
So the no. of fox is 20
Your final answer
No. of bear = 60
No. of rabbit= 10
No. of fox = 20
, so x+x=120
so 2x=120
x=120/2
x=60
so the no of bear = 60
In equation 2
let rabbit be y
then y+60=70
so y= 70-60
hence y = 10
So the no of rabbit = 10
In equation 3
let the no. of fox be z
z+10+60=90
z+70=90
z=90-70
z=20
So the no. of fox is 20
Your final answer
No. of bear = 60
No. of rabbit= 10
No. of fox = 20
