• x=9, x=-19

• x=4, x=-4

• x=9, x=-9

• x=0, x=5

What is the first step to solve the following equation?

-2|x + 3| = -10

• Set up 2 equations

  -2(x + 3) = 10

  -2(x + 3) = -10

• Add 2 to both sides

• Subtract 3 from both sides

• Divide by -2 on both sides

• No Solution

−2|−2r − 4| = -12

• x = 5 and x = 1

• x = -5 and x = -1

• x = -5 and x = 1

• No Solution

When do you set up 2 equations?

|x + 2| + 3 = 4

• That is the first step.

• After you subtract 3 from both sides.

• After you add 2 and 3.

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

Solve |x – 12| - 3 = 11.

• x = -2 and x = -26

• x = -2 and x = 26

• x = 3 and x = 25

• x = 4 and x = -7
