Question

For any number, y

Add one third of the number
Then subtract _____________ of the result.
The answer is y

Answer 1

`(3)/(12)`

Explanation:

Create an equation and solve for x:

`y + (1)/(3) y = (4)/(3) y\\(4)/(3)y - x((4)/(3)y) = y\\x = (3)/(12)`

Answer 2

y/3

Explanation:

According to the conditions :

y + y/3 - x = y

y + y/3 - y = x

(3y + y - 3y )/3 = x

y/3 = x
