Two ways to solve this question
First way: algebra with simultaneous equation
4x +2y=128
x+y=48
Solve this for x and y, which is the number of cat and bird respectively.
x=16
y=32

Second way: guess and check
Make a table with
X Y Number of legs

Eventually u will guess x=16 and y=32
Tedious but no algebra involved.
