A dog, a cat and a rabbit were friends.One day they planned to weigh themselves. The cat and the rabbit together weighed 10 kg, the dog and rabbit together weighed 20 kg and the dog and the cat together weighed 24 kg. What is their total weight together??

c+r =10

d+r=20

d+c=24

d+c+r = ?  

 

Add the first three equations together to get

 

2c + 2r + 2d = 54     now divide by 2

c+r+d = 27 kg
