Absolute Value in 1 Variable

Solve for x
∣ 2x + 9 ∣ = 15

• x = 3 
• x = 3   x = -6
• x = 3   x = -12
• x = 6   x = -12

An absolute value can NOT equal...

• a positive number
• a negative number

Solve for x 
|−2n| + 10 = −50

• {30, -30}
• {20,-20}
• {-5,5}
• No Solution

Solve for x
| m - 2 | < 8

• 9 > m > 8
• 2 < m < -6
• -6 < m < 10
• 0 > m < 0
