How many cases do you have after you remove the absolute value?
{-1,-7}
Practice makes perfect
An absolute value measures an expression's distance from a midpoint on a number line.
|x+4|= 3This equation means that the distance is 3, either in the positive direction or the negative direction.
|x+4|= 3 ⇒ lx+4= 3 x+4= - 3
To find the solutions to the absolute value equation, we need to solve both of these cases for x.
