for 2x+y=9 you do
-2 -2 (subtract two from both sides)
then you would get:
y=9-2x
(remember that when you move something to the other side you do the opposite equation)(in this case the opposite of positive is negative, so the 2x becomes negative)
-2 -2 (subtract two from both sides)
then you would get:
y=9-2x
(remember that when you move something to the other side you do the opposite equation)(in this case the opposite of positive is negative, so the 2x becomes negative)
