Schritte zur Lösung

∣ 3 x - 1 ∣ = 16

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x - 1 = - 16 or 3 x - 1 = 16

3 x - 1 = - 16 or 3 x - 1 = 16

x = - 5 or x = \frac{17}{3}

- 7 ∣ - 3 - 3 r ∣ = - 21

x^{2} - 5 = 1

∣ x + 5 ∣ - 1 = - 1

x^{2} + 2 x - 5 = 3

- 2 ∣ 5 x - 7 ∣ + 9 = - 7
