An absolute value measures an expression's distance from a midpoint on a number line.
|x-3|= 5
This equation means that the distance is 5, either in the positive direction or the negative direction.
|x-3|= 5 ⇒ lx-3= 5 x-3= - 5
To find the solutions to the absolute value equation, we need to solve both of these cases for x.
