I went through my textbook to double check how to do this problem, here is what I've done.
9 - (3x - 2) = 2
9 - 3x - 2 = 2
- 3x + 7 = 2
- 7 - 7
-3x = -5
divide both sides by -3
x = 5/3 (not simplified)
Now, the answers I get to choose from are:
a) -3/5
b) 3/5
c) 3
If I'm not mistaken, I'm doing this problem correctly. I asked a few people at my house, and they all said the teacher could have created a typo when showing which answers to choose from. I'm not sure though...
Any help would be awesome!
