The answer is #x<-6#

Explanation:

To solve that problem, first, you need to transpose 4

#-2x-4>8#
#-2x-4+4>8+4#
#-2x>12#
Next, we need to divide both sides by -2. But remember, when you divide an inequality problem, you need to change the inequality sign itself.
Meaning, if you divide the problem by negative and your inequality sign is like this, <, it will eventually be change to this, >.

#(-2x)/-2>12/-2#

#x<-6#
