Solve the inequality for x.

–8x – 16 < –72

A) x < 7
B) x < 11
C) x > 7
D) x > 11

x > 7

Step-by-step explanation:

–8x – 16 < –72

Add 16 to each side

–8x – 16+16 < –72+16

-8x < -56

Divide each side by -8, remembering to flip the inequality

-8x/-8 > -56/-8

x > 7

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
