Question

The container that holds the water for the football team is
1/3
full. After pouring out
6
gallons of water, it is
1/9
full. How many gallons can the container hold?

Answer 1

1/3x - 6 = 1/9x
-6 = 1/9x - 1/3x
-6 = 1/9x - 3/9x
-6 = - 2/9x
-6/(-2/9) = x
-6 * -9/2 = x
54/2 = x
27 = x

check..
1/3(27) - 6 = 1/9(27)
9 - 6 = 3
3 = 3 (correct)

tank holds 27 gallons
