Ron is twice as old as his nephew. The sum of their ages is 108. How old is Ron?

Parth (parthkohli):

If the nephew is x years, then Ron is 2x. Let's set up an equation here, aight? \(\Large \color{MidnightBlue}{\Rightarrow 2x + x = 108 }\) \(\Large \color{MidnightBlue}{\Rightarrow 3x = 108 }\) \(\Large \color{MidnightBlue}{\Rightarrow x = 36 }\) Recall that Ron is 2x and x = 36. Ron is 2 * 36 = 72 years old.
