Slide 1:More Examples for Solving Absolute Value Equations


Slide 2:Remember, you should have TWO answers to each equation: 4x – 1 = 6 4x – 1 = -6 Solve 4x = 7 x = 7/4 4x = -5 x = -5/4 Set up 2 equations.


Slide 3:“Isolate” the absolute value first. Two equations -2x – 5 = 5 -2x – 5 = -5 Solve -2x = 10 x = -5 -2x = 0 x = 0


Slide 4:BUT… Be careful… Can’t be done!!! A number does not exist that has an absolute value equal to a negative number!
