#x > 7#

Explanation:

Things you can do with an inequality which maintain the inequality (and its orientation):

  • Add or subtract the same amount to both sides;
  • Multiply or divide both sides by the same amount provided that amount is greater than zero.

In this case:
we are given #x+3 > 10#
so
we can subtract #3# from both sides to get
#color(white)("XXX")x > 7#
