Since this is an inequality, we must simplify the right side to compare to 18.

18 [tex] \geq [/tex] -8(6n-8) + 7((3n+5)
18 [tex] \geq [/tex] -48n + 64 + 21n + 35
18 [tex] \geq [/tex] -27n + 99
-81 [tex] \geq [/tex] -27n
3 [tex] \geq [/tex] n

Since 'n' is less than or equal to 3, you would have a solid dot on the 3 with a line going to the left.
