Question

There are twice as many cows as goats on a farm.there is a total of 1116 legs how many goats are there

Answer 1

cows and goats have 4 leggs each

so

c=cows
g=goats

c=2g

4c+4g=1116
4(c+g)=1116
divide 2nd equation by 4
c+g=279

sub 2g for c
2g+g=279
3g=279
divide both sides by 3
g=93

93 goats
