4. Solving Absolute Value Equations
Sign In
How many cases do you have after you remove the absolute value?
Solutions: x= 10 and x=- 10
Number Line:
This 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.
