Schritte zur Lösung

∣ - 2 x ∣ = 19

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 x = - 19 or - 2 x = 19

- 2 x = - 19 or - 2 x = 19

x = - \frac{19}{2} or x = \frac{19}{2}

- 2 ∣ x - 3 ∣ = 4

∣ 2 x - 3 ∣ = 1 - x

x^{6} ∣ - 8 + 5 x ∣ - 4 = 38

∣ 3 x + 14 ∣ = - 16

∣ a ∣ = a, a < 0
