What is the reason that absolute value is always written as a positive?

• Absolute value is talking about numbers so it must be positive.
• Absolute value does not always have to be positive.
• Absolute value is like a clock it has only positive numbers.
• Absolute value is talking about distance, distance is always measured by positive numbers.

∣ 2x + 9 ∣ = 15

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

|-4x+12| = 0

• x=3
• x=-3
• x=4
• x=-4

Solve the absolute value equation. 

• x = 0 or x = 6
• x = 10 or x = -4
• x = 6 or x = -6
• x = 8 or x = -2
