Answer by vleith(2983) (Show Source): You can put this solution on YOUR website!
let c be the number of chickens and r be the number of rabbits.
You are told

You are also told the total number of legs is 260. So
since each chicken has 2 legs and each rabbit has 4
Use those two equations to solve for c
from equation 1.
substitute in the value for r in the previous equation
now simplfoy and solve for c

so you have 70 chickens and 30 rabbits.
Check your answer, does 2*70 + 4*30 = 260?
