#x > 7#

Use the necessary mathematics to isolate and solve for #x# while keeping the inequality balanced.

First subtract 9 from each side of the inequality:

#18x + 9 - 9 > 135 - 9#

#18x + 0 > 126#

#18x > 126#

Next divide each side of the inequality by 18:

#(18x)/18 > 126/18#

#1x > 7#

#x > 7#
