A group of pigs and chickens are in the backyard of your house.
when counted by heads the number is 15.
when counted by legs the number is 44.
How many pigs and chickens are there?
there is 8 chicken and 7 pigs..
8 chickens have 16 legs..
7 pigs have 28 legs..
Let X = number of pigs and Y = number of chichen
Then, we can write the following equations.
X + Y = 15
4X + 2Y = 44
Solving the system, X = 7 , Y = 8
A drove of sheep and chickens have a total of 99 heads and feet.
There are twice as many chickens as sheep.
