3x + 9 = 7x - 11

How do I solve this?
You said subtract three x from each side, then all eleven to both side then divide each side by 10?

I'm confused...

1. If you followed those instructions, even without the typos, I'm sure you were confused!

3x + 9 = 7x - 11
subtract 3x:
9 = 4x-11
20 = 4x
divide by 4:
5 = x
