use cross products
(3r+6) *2 = 9*(2r-4)
6r+12 = 18r-36 distribute

Answer:
The answer is 6
Step-by-step explanation:
All you have to do is take 8x-4 and then combine it with 6x+8 like this...
8x-4=6x+8.
Then you have to add 4 to 8 and you will get 12.
Then you subtract 6 from 8 and get 2. So your equation will look like this...
2x=12
Then you divide 12 by 2 and you get 6 because 6 x 2 is 12.
HOPE THIS HELPS!!!!!!
