Is that right?

Answer 1

I don't really understand your answer.

How many animals have 2 legs?
How many animals have 4 legs?

Answer 2

10 with 2 legs and 4 with 4 legs

Answer 3

Correction: Should be 8 animals with 4 legs and 2 animals with 2 legs.

Answer 4

That can't be. There are only 10 animals.

Answer 5

x=number of animals with 4 legs
y=number of animals with 2 legs
36= total number of legs
10= total number of animals

x+y=10
x=10-y

4x+2y=36
4(10-y)+2y=36
40-4y+2y=36
-2y=-4
y=2
x=8
