Solve the inequality for x.

-3x - 6 < 15

A) x < - 3

Eliminate

B) x < - 7

C) x > - 3

D) x > - 7

Option D, x > - 7

Step-by-step explanation:

Step 1: Add 6 to both sides

-3x - 6 + 6 < 15 + 6

-3x < 21

Step 2: Divide both sides by - 3

-3x / - 3 < 21 / - 3

Since you divided by a negative, you need to flip the sign

x > - 7

Answer: Option D, x > - 7

D) x > - 7

Step-by-step explanation:

-3x - 6 < 15

Add 6 to each side

-3x - 6+6 < 15+6

-3x < 21

Divide each side by - 3, remembering to flip the inequality

-3x/-3 > 21/-3

x >-7
