Question

The container that holds the water for the football team is 7/10 full. After pouring out 5 gallons of water, it is 1/2 full. How many gallons can the container hold?

Answer 1

7/10x - 5 = 1/2x
7/10x - 1/2x = 5
7/10x - 5/10x = 5
2/10x = 5
x = 5 / (2/10)
x = 5 * 10/2
x = 50/2
x = 25 gallons <===

Answer 2

(7/10)X - 5 - (1/2)X
(7/10)X - (5/10)X = 5
(2/10)X = 5
X = 25 gallons capacity
