I'm confused as to where the -3 came as opposed to a 3 + 5.

Do you mean near the 3min mark in the video?
This is because I wanted to get y all by itself. To do so I had to subtract 3x from the left hand side; whatever you do to one side you have to do the the other, so thats what it is a -3 on the right.
