Solving equations with absolute value

|−4 + 5x| = 16

• {16/5,12/5}
• {4,-5}
• {-12/5, 4}
• 4

|6 - 2k| = 18

• k = -6
• k = -6, k = 12
• k = -6, k = -12
• k = -6, k = 5

|-2 - 4n| = 34

• n = -9, n = 8
• n = 9, n = 8
• n = -9
• n = 8

Solve:

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

Solve |x – 12| - 3 = 11.

• x = -2, -26

• x = -2, 26

• x = 3, 25

• x = 4, -7
