#x# > #-7/2#

Explanation:

We want to get #x# alone in this inequality. To do this, we divide each side by -2 (but remember, when you divide or multiply by a negative number in an inequality, you switch the sign)

#-2x# < #7# (divide each side by -2)

Divide each side by #-2# and switch the inequality sign:

#x# > #-7/2#
