Unit 3 Review PreAlg

Simplify the following expression:
-6x + 4(-x - 3)

• -2x - 12
• 10x + 12
• -10x - 12
• -2x + 12

–3r – 6(–7 – 10r)                                                                                                                  

• –63r – 42
• – 63r + 42
• – 13r + 42
• 57r + 42

Solve for x:
4 - 2(x - 3) = 24

• - 7
• 7
• 14
• - 14

Solve for x:
5x - 14 = 8x + 4

• x = 6
• x = -6
• x = -18/13
• x = 10/3

Solve the equation:
7x - 4 = 3 + 8x

• x = 7
• x = -7
• x = 2/7
• x = 11
