Basic Absolute Value Equations

Solve for x
l 2x−1 l +4 = 8 

• x = 2.5 and x = -1.5

• x = 2 and x = -1

• x = -2 and x = 9

• No Solution

Solve for x
l 2x−1 l = 9

• x = 5 and x =-4

• x = 5 and x = -5

• Only x = 5

• No Solution

Solve the absolute value equation: |3x - 9| = 0

Solve the absolute value equation: |2y - 4| = 8

Solve the absolute value equation. 

• {7}

• {-7, 7}

• {0, 7}

• No Solution

|8 - 4x| = 16

• x = -2, x = -6

• x = 2 , x = 24

• x = -2, x = 6

• No Solution
