Answer:
n<6, see image, shade to the left
Step-by-step explanation:
Divide both sides by -2.
If you divide be a negative, you must reverse the inequality symbol.
You can see that the inequality symbol is "pointing" at the n. I just turned it back around again bc it's easier to read that way. It is still "pointing" at the n, so it means the same thing. It says, "n is less than 6" What numbers are less than 6? Like 5, 4, 3, etc. Even 5.25 and 5.9 are less than 6. So put an open circle on the 6 (some classes/teachers/books put a parenthesis instead of an open circle, face it towards the shading) Then shade to the left. See image.
