Schritte zur Lösung

∣ 3 x - 1 ∣ = 11

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x - 1 = - 11 or 3 x - 1 = 11

3 x - 1 = - 11 or 3 x - 1 = 11

x = - \frac{10}{3} or x = 4

∣ 3 x - 1 ∣ = 16

- 7 ∣ - 3 - 3 r ∣ = - 21

x^{2} - 5 = 1

∣ x + 5 ∣ - 1 = - 1

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