Solve the inequality.

• 4 < y < 18

• - 7 < y < 4

• - 4 < y < 24

• -2 < y < 18

• x > 2 or x < 6
• x > 6 or x < 2
• - 2 < x < 6
• x > 9 or x < 20/7

Solve for x
l 2x−1 l +4 = 8 

• x = 2.5 and x = -1.5
• x = 2 and x = -1
• x = -2 and x = 9
• No Solution

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k
