Let the ratio be x
So Paul's age = 2x
and Luis's age = 3x
The sum of their ages is 35 years
So, 2x + 3x = 35
5x = 35 (add the like terms)
To find x, divide both side by 5
[tex] \frac{5x}{5}= \frac{35}{5} [/tex]
x = 7
Paul's age = 2x = 2(7) = 14 yrs
Luis's age = 3x = 3(7) = 21 yrs
So age of Paul's is 14 yrs and age of Luis's is 21 yrs.
