your technique seems fine
typos do occur on occasion
Hi, I'm trying to solve this problem and I can't seem to come up with the answer that the answer book says.
It is 3 = -20/3 + b
So I want to solve for b
I add 20/3 to both sides so I get 3 + 20/3 = b
When I make the same denominators, I get 9/3 + 20/3 to be 29/3 = b
The answer book says 50/3.
What am I doing wrong here?
Thank you
