Solve for x
l 2x−1 l = 9

• x = 5 and x =-4
• x = 5 and x = -5
• Only x = 5
• No Solution

Solve for x
l x−6 l + 4= 10

• x = 12 and x = 0
• x = 3 and x = -3
• x = -12 and x = 0
• No Solution

Solve:

• {24}
• {-6, -8}
• {16, 4}
• {24, -24}

• {4, -4}
• {9, -9}
• {5, -9}
• {13, -1}

−2|−2r − 4| = -12

• {3,1}

• {-5,1}

• {-3}

• No Solution
