Question

If you add 125 to


`(1)/(2)`
of a number, the result is 450. Which equation would help find the original number? ​

Answer 1

2.
`(1)/(2)x+125=450`

Explanation:

We can use x to mean the number not known. Let's start by using
`(1)/(2)` of a number which would be
`(1)/(2)x` because the number here is signified by x. Then you would add 125 to that answer which would be shown by
`(1)/(2)x+125`. All of it equals 450, so it would be written as
`(1)/(2)x+125=450`
