Answer:

#x > 8#

Explanation:

If #7x-2 > 54#
then
#color(white)("XXXX")#(adding 2 to each side)
#7x > 56#
and
#color(white)("XXXX")#(dividing both sides by 7)
#x > 8#

Remember:

  1. You can add or subtract any constant to/from both sides of an inequality without effecting the validity of the inequality.
  2. You can multiply or divide both sides of an inequality by any value greater than 0 without effecting the validity of the inequality.
