Let's assume
number of birds with 2 wings is x
number of birds with 4 wings is y
A nature museum has 2008 specimens of early birds
so,

Total of wings of 2 wings bird =2x
Total of wings of 4 wings bird =4y
The specimens have a total of 4384 wings
so, we get

we can divide both sides by 2

so, we get system of equations as


we can solve for x and y
We can subtract both equations





so,
number of birds with 2 wings is 1824
number of birds with 4 wings is 184.............Answer
74 - 96 million cats are owned
