Problema Solution
Animals running around farm. Rachel counted 35 heads and 94 feet. How many llamas (4 feet) and how many ostriches (2 feet) are there?
Answer provided by our tutors
let
x = the number of llamas on the farm
y = the number of ostriches on the farm
Rachel counted 35 heads and 94 feet
x + y = 34
4x + 2y = 94 divide both sides by 2
2x + y = 47
by solving the system of equations
x + y = 34
2x + y = 47
we find
x = 13 llamas
y = 21 ostriches
