An absolute value measures an expression's distance from a midpoint on a number line.
|t|= 5.4
This equation means that the distance is 5.4, either in the positive direction or the negative direction.
|t|= 5.4 ⇒ lt= 5.4 t= - 5.4
Both 5.4 and -5.4 are solutions to the absolute value equation but the only positive solution is 5.4.
