Aunt Wang raised many chickens and rabbits. It is known that there are 13 more chickens and 16 more feet than rabbits. How many chickens and rabbits are there?
Suppose there are x rabbits, then there are (x + 13) chickens, (x + 13) × 2-4x = 16 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 2x = 10 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp
There are 150 chickens and rabbits in the same cage. How many chickens and rabbits are there?
Analysis: chicken leg is equal to rabbit leg, so the number of chicken is twice that of rabbit. If the number of rabbit is regarded as one, the total number is three
Rabbit: 150 / (1 + 2) = 50
Chicken: 150-50 = 100
Chicken and rabbit are in the same cage. There are two more rabbits than chicken. There are 68 chicken legs and rabbit legs. How many of the two animals are there
Suppose there are x rabbits
2*（x-2）+4x=68
x=12
There are 12 rabbits and 10 chickens
