Question

I am thinking of a number.i add 62 to the number and divide the total by 7.the result is 4 less than the number 1 thought of.what was the number​

Answer 1

15

Explanation:

let the number be n, then

`(n+62)/(7)` = n - 4 ( multiply both sides by 7 to clear the fraction )

n + 62 = 7n - 28 ( subtract n from both sides )

62 = 6n - 28 ( add 28 to both sides )

90 = 6n ( divide both sides by 6 )

15 = n

That is the number is 15
