-2(x + 3) - 5 = 11

• x = - 11
• x = 2
• x = 11
• x = -2

4x + 2(x - 6) = 12

• x = 6
• x = 4
• x = 2
• x = -2

-3 − 6(4x + 6) > -111

• x > 3
• x < 3
• x < -3
• x > -3

• No Solution 

• x = 8

• x = -5

• x = 7

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

Which of the following equations would have infinite solutions?

• 3x + 9 = 2x + 9
• 8x = 8x + 4
• 3(4x + 4) = 12x +4
• -5x + 10 = 10 - 5x
