Farmer Brown had ducks and cows. One day she noticed that the animals had a total of 12 heads and 32 feet. How many of the animals were ducks and how many were cows?

D + C = 12 (number of heads)
2D + 4C = 32 (number of feet)
Solve for D and C, using algebra. 
pooop

there are 4 cows and 8 ducks because if you  3224=8 and 8 divided by 2 = 4 cows
so my answer is 4 cows and 8 ducks 
aw poop. it doesn't exactly tell you how to do it. I need to write an equation for this question :( my teacher wont take this xD

there are 4 cows and 8 ducks

8 ducks and 4 cows
D + C = 12
8 + 4 = 12
2 D + 4 C = 32
2(8)+ 4(4)= 32
16 + 16 = 32
32 = 32 
14(14)14
