Exercise 14 Page 196

How many cases do you have after you remove the absolute value?

-3 or 3

Practice makes perfect

An absolute value measures an expression's distance from 0 on a number line. |x|= 3 This equation means that the distance is 3, either in the positive direction or the negative direction. |x|= 3 ⇒ lx= 3 x= - 3 Both -3 and 3 are solutions to the absolute value equation.
