Google translate gives:

"There are a few cats and ducks. 48 feet, 32 eyes. How many cats and how many ducks are there?"

 

c = cats,  d = ducks

 

4c + 2d = 48

2c + 2d = 32

 

2c = 48 - 32   so  2c = 16   so c = 8

 

16 + 2d = 32   so 2d = 32 - 16  so  2d = 16  so d = 8

 

There are 8 cats and 8 ducks.

 

有8隻貓和8隻鴨子
