Hi, 
Let x, y and z  represent Elmira's, Geoff's and Rae's ages respectively 
 x + y + z = 82   
 Elmira doubles her own age, it will equal Doug's age. 
Elmira adds six to Geoffs age, it will equal Doug's age. 
 2x = y + 6   0r  x = y/2 + 3 
subtracts 8 from Rae's age, it will equal Doug's age. 
y + 6 = z - 8 
   z = y+14 
(y/2 + 3) + y + ( y+14) = 82 
       
            y =   = 26, Geoff'a age.   Doug is 32 
CHECKING our answer*** 
 16 + 26 + 40 = 82 
Wish You the Best in your Studies.
