Hello, all. I am trying to solve a limit question and although I am aware of the correct answer, I'm not quite sure how to arrive at it.
For x approaches 7, (7 - x) / (x - 7)
I know the answer is (-1), but I am not sure how to arrive there. It seems to me that both terms would cancel out and the answer would be 1.
Thanks in advance for any replies!
