S is x
R is x+4
in five years, S will be x+5 and R will be x+9 for a sum of 2x+14=30
2x=16
x=8
S is 8
R is 12
in 5 years, they will be 13 and 17.

If a formal algebraic solution is not required, it might go something like this.
Since the sum of their ages 5 years from now will be 30, the sum of their ages now is 30-(5+5) = 20.
If they were now the same age and the sum of their ages is 20, their ages would be 10 and 10.
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.
ANSWER: Rose is 12 and Samuel is 8.
