5

∣ 5 - 8 x ∣ = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 - 8 x = - 6 or 5 - 8 x = 6

5 - 8 x = - 6 or 5 - 8 x = 6

x = - \frac{1}{8} or x = \frac{11}{8}

- 2 ∣ 3 x - 9 ∣ + 1 = - 17

∣ 8 x + 5 ∣ + 5 = 2

1 - ∣ 3 x - 2 ∣ = 10

∣ 3 + 7 k ∣ - 4 = 28

2 x + ∣ x - 6 ∣ = 30
