Explanation of the solution steps:
Call the rabbit number:x(con)(x>0)
=> The number of rabbit feet is: 2x(foot)
=> The number of chickens is: 2x(chickens)
=> The number of chicken feet is: x/2.2=x(foot)
Since there are a total of 210 chicken and rabbit legs combined, the number of rabbits is:
2x+x=210
⇒3x=210
⇒x=210/3=70
So the rabbits are: 70 (rabit)
