How many cases do you have after you remove the absolute value?
Solutions: x= 10 and x=- 10 Number Line:
Practice makes perfect
An absolute value measures an expression's distance from a midpoint on a number line.
|x|= 10This equation means that the distance is 10, either in the positive direction or the negative direction.
|x|= 10 ⇒ lx= 10 x= -10
Both 10 and - 10 are solutions to the absolute value equation. Let's graph these solutions on a number line.
