Question

One-half of a number,
increased by 69 is 74.
What is the number?

Answer 1

Let the number be x
1/2 x + 69 = 74
1/2 x= 74 - 69
1/2 x = 5
x = 2*5
x= 10

Answer 2

10

Explanation:

let the number be n then half the number is
`(1)/(2)` n , so

`(1)/(2)` n + 69 = 74 ( subtract 69 from both sides )

`(1)/(2)` n = 5 ( multiply both sides by 2 to clear the fraction )

n = 10

Thus the number is 10
