Simplify the following expression:
3 + 5x + 8 - 2x

• -3x² - 11
• 3x² + 11
• 11 - 3x
• 11 + 3x

Solve for s:

• s= 10

• s= -6

• s= 18

• s=-10

6x + 2x + 1 + 4

• 8x + 5 
• 2x - 3
• 4x - 2
• 8x + 12 

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

x/12 - 5 = -6

• -12
• -19
• 11
• 15

Solve for k:
3k + 5 = 23

• k = 4
• k = 5
• k = 6
• k = 7

|-20|

• 20
• -20

| –3 |

• 3
• -3
• 0.30
• 30

Solve | 3x - 6 | - 9 = -3

• No Solution

• x = 0 or x = 4

• x = 2 or x = -2

• x = -4 or x = 4
