#n> -107#

Explanation:

Work your way towards isolating #n#

Start by adding 9 to both sides of the inequalty.
#-n<107#

Divide by # -1# to completely isolate #n.# But when you divide by a negative in an inequality, the inequality symbol flips.

#n> -107#

So, in this case, the inequality changed from #" less than " (<) " to greater than " (>)#
