ABSOLUTE VALUE EQUATIONS

3 types of absolute value sentences.

| x | = 3

| x | > 3

| x | < 3


| x | = 3

What numbers have an absolute value of 3?

x = -3 or x = 3



Solve: | x | = 10

x = -10 or x = 10



Solve: | x | = 7

x = -7 or x = 7



Solve: | x | = 27

x = -27 or x = 27



Solve: | x + 5| = 7

x + 5 = -7 or x + 5 = 7-5 -5 -5 -5

x = -12 or x = 2



Solve: | 2x + 1| = 3

2x + 1 = -3 or 2x + 1 = 3-1 -1 -1 -1

2x = -4 or 2x = 2


x = -2 or x = 1


Solve: | x | = -3

No Solution
