Solve for x

8+2 lx−4l=18

• x = 9 and x =-1

• x = 9 and x = -9

• x= 7 and x = -11

• x = 5.8 and x = 2.2

−2|−2r − 4| = -12

• x = 5 and x = -1

• x = -5 and x = 1

• x = -5

• No Solution

| -8x | < 8

What is the correct first step?

• separate into two inequalities with an "and"

• separate into two inequalities with an "or"

• divide both sides by -8

• add 8 to both sides
