Question 1148701
<br>
If a formal algebraic solution is not required, it might go something like this.<br>
Since the sum of their ages 5 years from now will be 30, the sum of their ages now is 30-(5+5) = 20.<br>
If they were now the same age and the sum of their ages is 20, their ages would be 10 and 10.<br>
To make a sum of the two ages that is 20 with a difference of 4 between the two ages, add and subtract 2 from 10 to get 12 and 8.<br>
ANSWER: Rose is 12 and Samuel is 8.
