Answer 2

I am unsure how you would make two problems about this...

Answer 3

kk thx anyway

Answer 4

Wait nvm.

Answer 5

x+y=11
4x+2y=34

Answer 6

Wait a min. Do you want the number of animals (which is already given - 11) or number of cats & birds???

Assuming you want number of cats & birds.

x = cats
y = birds

Solve for
4x + 2y = 34
(4 legs per cat & 2 legs per bird. 34 in all)
x + y = 11
(total no of pets = 11)

Solve the simultaneous equations ;)
