How many cases do we have after we remove the absolute value?
{-1,- 1/3}
Practice makes perfect
An absolute value measures an expression's distance from a midpoint on a number line.
|3m+2|= 1This equation means that the distance is 1, either in the positive direction or the negative direction.
|3m+2|= 1 ⇒ l3m+2= 1 3m+2= - 1
To find the solutions to the absolute value equation, we need to solve both of these cases for m.
