Solve for x
l 5x l = 40

• x = 8 and x =-8

• x = 35 and x = -35

• Only x = 8

• No Solution

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

| x – 3 |= 0

• 3

• -3

• {-3, 3}

• no solution

Solve |x – 12| - 3 = 11.

• x = -2
  x = -26

• x = -2
  x = 26

• x = 3
  x = 25

• x = 4
  x =  -7
