First multiply both sides by 3 to get rid of the fraction.

Yes, but in order to put on a line it should be in the proper equation. Rewrite your given problem so that x is on one side.

your 6 is correct, but your inequality sign should have been switched.

as a hint, closed is "inclusive" so if you have = to also, than it is closed.
Your direction is what I was getting you to change....

yes  you just had the line going in the wrong direction.....final equation is less than or equal to so therefore your lines goes to the left
