Answer:
x > -4
Explanation:
What you do is in order to get the x by itself you need to do the opposite of -12 which is just +12 so you need to add 12 to both sides. You should end up with something like this:
x -12 + 12 < -16 + 12
x < -4
So, that should be your answer. Hope this helps :) Have a good day!!
