4. Solving Absolute Value Equations
Sign In
How many cases do you have after you remove the absolute value?
Solutions: x=13 and x=- 13
Number Line:
This equation means that the distance is 13, either in the positive direction or the negative direction. |x|= 13 ⇒ lx= 13 x= - 13 Both 13 and - 13 are solutions to the absolute value equation. Let's graph these solutions on a number line.
