Q. In a pasture are horses and chickens if there are a total of 28 animals and 80 legs: how many chickens and horses?12 horses, 16 chickens16 horses, 12 chickens18 horses, 10 chickens10 horses, 18 chickens
Identify variables: Identify the variables: Let h represent the number of horses and c represent the number of chickens.
Set up equations: Set up the equations based on the total number of animals and the total number of legs: 1. h+c=28 (total animals)2. 4h+2c=80 (total legs)
Solve for c: Solve the first equation for one of the variables. Let's solve for c:c=28−h
Substitute c: Substitute c=28−h into the second equation:4h+2(28−h)=80
Simplify and solve: Simplify and solve for h:4h+56−2h=802h+56=802h=24h=12
Substitute h: Substitute h=12 back into the equation for c:c=28−12c=16
