How come the father age is 3x

Is not 1/3x?

Of course, you can do another way via the 1/3 way instead, whereby 1/3 (jolin's age) = Joseph's age. However, you will run into fractions that can lead to a higher chance of mistakes. So, to make things less complicated (by making all of the algebra whole numbers), I chose to times three of Joseph's age.

Hope this clarifies everything! ;))

Opps sorry. I mean Joseph age is 1/3 of his sister age so i need to x3

Thanks
