A farmer has chickens and cows. You ask the farmer how many chickens he has, and how many cows he has. The farmer has 28 healthy
crimeas [40]
Set the number of chickens as x and number of cows as <span>y
</span>so the farmer has total 28 animals
so x+y=28 
you know that since the animals are healthy
chickens will have 2 legs    and
cows will have 4 legs
the total number of legs are 64
so 2x+4y=64
since you want to find the number of cows 
so from the first equation <span>x+y=28
</span>we will get another equation <span>x=28-y
</span>then plug into <span>2x+4y=64
2(28-y)+4y=64
56-2y+4y=64
56+2y=64
-56      -56
2y=8
y=4
