Now this should be the solution once solving.
The attached picture below shows the graph.
Hope this helps!
If you imagine this line on a grid, you get 18 units below the 0 and 18 units above the 0, which means you must add them together and get your answer as 36 units. I hope this helps!
-8-n=-6n+12
+8. +8
-n=-6n+20
+6n +6n
5n=20
5. 5
n=4
