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.

Solve for x:

ax - b = cx + d

• x = (a-c)/(b+d)

• x = (b+d)/(a-c)

• x = (b+d)/(a+c)

• x = (a+c)/(b-d)
