Subtract 2 from both sides.
8n - 10n < 18
Combine 8n and -10n
-2n
-2n < 18
Divide both sides by -2
N < -9
Post me back if you have any problems or more questions.

Except remember that when dividing (or multiplying) both sides by a negative number, you reverse the sense of the inequality.
You can see, e.g. that n = -10 satisfies the proposed conclusion (n < -9) but doesn't satisfy the original inequality.
