Answer:

If we take Ryan's age as 'x' then we have Aaron's age as '2x'

Now, we have the sum of their ages after 3 years as 30.

So  according to question, we can prepare an equation which is

2x+3+x+3 = 30

= 3x+6 = 30

= 3x = 30-6

= 3x = 24

= x = 24÷3

= x = 8

Thus, Ryan' is 8 years old now.

Now we need to find Aaron's age, and this can be done easily as we have already made an expression fore Aarons age, i.e., '2x'

So 2x= 2×8

= 16.

So we have Aaron's age-16,

Ryan's age-8

Ok so first, let’s see it this way

Aaron: x *2
Ryan: x

So basically 3 in total. Since 30 is already divisible by three we can go from there. Then we will get original age.

30/3 = 10

Aaron = 10 *2
Ryan = 10

This is their ages AFTER the three years. So now, we just subtract to find original age.

20-3= 17
20-3 = 7

Aaron is 17.
Ryan is 7.
