Answer:
C
Step-by-step explanation:
It is okay to take the inverse of both side given that you remember to exclude the value that make the denominator zero which is in this case r=-1
Just plot the points on a graph.
Add 5 to both sides
5-5+x/3=5-11
0+x/3=-6
x/3=-6
times both sides by 3
3x/3=-18
x=-18
