Answer:

x >-4

Step-by-step explanation:

-2x<8

Divide each side by -2, remembering that when we divide by a negative we flip the inequality

-2x/-2 >8/-2

x >-4

Answer:

Option C, x > -4

Step-by-step explanation:

Step 1:  Divide both sides by -2

-2x < 8

-2x / -2 < 8 / -2

Since you divide by a negative, you must flip the sign

-2x / -2 < 8 / -2

x > -4

Answer:  Option C, x > -4
