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!
