YOUR website!

x=pigeons

y=rabbits

x+y=20

2x+4y=48

=======

2x+4y=48

-2x-2y=-40 (multiply it by -2)

2y=8

y=4 rabbits

x=16 pigeons

that is 20 heads and 4*4+16*2=48 as

Answer 2

Answer:

4 rabbits

Step-by-step explanation:

let there are X piegons and Y rabbits

so, for heads,

X + Y = 20 (1)

for feet, 2X +4Y = 48. (2)

multiply (1) by 2 and subtract it from (2)

we get , Y = 4 and X = 16
