There are three times as many geese as hares on the farm. They have a total of 60 feet. How many geese are on the farm?

Correct answer:

n =  18

Step-by-step explanation:


n = 3z
2n + 4z = 60

n = 3·z
2·n + 4·z = 60

n-3z = 0
2n+4z = 60

Pivot: Row 1 ↔ Row 2
2n+4z = 60
n-3z = 0

Row 2 - 1/2 · Row 1 → Row 2
2n+4z = 60
-5z = -30


z = -30/-5 = 6
n = 60-4z/2 = 60-4 · 6/2 = 18

n = 18
z = 6
