Absolute Value and Literal Equations

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.

ax + c = R

(solve for x) 

• 
  

  $x=\frac{R}{a}-\frac{c}{a}$

• x = $\frac{R}{a}-c$

• x = R - C- a

• $x=\frac{R}{a}+\frac{c}{a}$

Solve for x. 
x + 7g = 9

• x = 9 - 7g
• x = 9 / 7g
• x = 9 + 7g
• x = 7g - 9
