r=2e and (r+6)=3(a+6) and a=e-8

r=2e, r+6=3a+18, a=e-8

r=2e, r=3a+12, a=e-8 

since r=r we can say

2e=3a+12, using a=e-8 in this we get:

2e=3(e-8)+12

2e=3e-24+12

2e=3e-12

-e=-12

e=12, since  a=e-8 

a=4, since r=2e

r=24

so

Robin is 24 years old, Earl is 12 years old, and Adam is 4 years old.
