I have an example from the book, but I don't quite understand it.
4x-6y=12 I need to get it into y=Mx+b form so that I can graph it, but I get lost between steps 1 and 2. I know I should re-arrange the equation, but why do I switch the +/- signs?
These are the steps as they appear in the book:
4x-6y=12
step 1) 4x=6y+12 ( the sign changes from + to - )
step 2) 6y=4x - 12
step 3) 6y=4x-12
step 4) y=(4/6)x-12/6
solution: y=(2/3)x-2
could you explain the steps to me and why I do what I do in each step. ie:switching signs
