Answer:


x\:>\:4 or
x\:<\:-4

Explanation:

The given absolute value inequality is
-2|x|\:<\:-8

Divide both sides of the inequality by -2 and reverse the inequality sign:


|x|\:>\:4

By the definition of the absolute value function;

Either
x\:>\:4 or
-x\:>\:4

Divide through the rightmost inequality by -1 and reverse the sign.

This implies that:


x\:>\:4 or
x\:<\:-4
