Question

Kellie thinks of a number, then doubles the number, and then multiplies the result by 3. If her final number is 65 more than her original number, then what was her original number?

Answer 1

Step-by-step explanation:

let kellie's number be x

so, 2x*3=65+x

6x= 65+x

6x-x= 65

5x= 65

x= 65/5

x= 13
