R = N+13
R+9 = 2(N+9) substitute for R:
N+13+9 = 2(N+9)
N+22 = 2N+18
4 = N
switch sides
N = 4
Nash is 4 years old and Rod is 4+13 = 17
In 9 years:
N = 4+9 = 13
R = 17+9 = 26
In 9 years Rod will be twice as old as Nash:
13 x 2 = 26 Correct

system%28r-n=13%2Cr%2B9=2%28n%2B9%29%29

system%28r-n=13%2Cr%2B9=2n%2B18%29

system%28r-n=13%2Cr-2n=9%29

=============
The age difference is 13.
2x --> 26 & 13
