Ninth:

Meaning:

Helga's Age is: 24

And

Julie's Age is: 12

Answer 2

Explanation:

let Julie's age be x,

Let Helga's age be 2x-6 since she's 6 years younger than 2times of Julie's age.

Which implies that the sum of Julie's age to that of Halga = x + 2x -6

Implies x +2x -6 =36

Collect like terms

x + 2x= 36+6

3x=42

Divide both side by 3

X=16
