∣ 2x + 9 ∣ = 15

• x = 3 
• x = 3
  x = -6
• x = 3
  x = -12
• x = 6
  x = -12

Solve |x – 12| - 3 = 11.

• x = -2
  x = -26
• x = -2
  x = 26
• x = 3
  x = 25
• x = 4
  x =  -7

• (2.5+h)f
• g=1
• f(5+h)/2
• (5f+h) / 2

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

Rachel and Sharon are splitting up their Pokemon cards.  Rachel has 4 fewer than 3 times as many as Sharon.  Together they have 100 cards.  Which equation could be used to solve for how many cards Sharon had originally?

• n + (3n - 4) = 100
• n - (3n - 4) = 100
• n + (4 - 3n) = 100
• 4 - 3n = 100

Solve: 5x - 14 = 8x + 4

• 6
• -6
• -18/13
• 10/3

-8<2(x+4) or -3x+4>x-4

• No solutions
• x<-8 or x<2
•  x>-8 or x<2
• x<-8 and x<2
