Subtract 5n from both sides

5-9n <8

Subtract 5 from both sides

-9n <3

Divide both sides by negative 9.

n <1/3

To check:
5-4 (1/3)<8-5 (1/3)




OR



Add 4n to both sides

5 <8-n

Subtract 8 from both sides

-3 <-n
Divide both sides by negative 1

3 <n

To check:

5-4 (3)<8-5 (3)
-7 < -7


The first way is your right answer.
