Never "flip" anything.  Simplify your life by not having to remember.

-6g + 3g + 12 > -18

Simplify variables.

-3g + 12 > -18

ADD 18

-3g + 30 > 0

ADD 3g

30 > 3g

Divide by 10

10 > g

No "flipping" of anything.  OR, this explains why the silly "flipping" is necessary and works.
