What are you trying to figure out here?
If you are trying to solve for y as a function of x:
first add -3x to both sides
3 x - 3 x - 6 y = -3 x + 30
or
-6 y = -3 x + 30
then divide both sides by -6
(-6/-6) y = (-3/-6) x = 30/(-6)
which is
y = 1/2 x - 5
first add -3x to both sides
3 x - 3 x - 6 y = -3 x + 30
or
-6 y = -3 x + 30
then divide both sides by -6
(-6/-6) y = (-3/-6) x = 30/(-6)
which is
y = 1/2 x - 5
