Schritte zur Lösung

∣ 4 x - 4 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x - 4 = - 15 or 4 x - 4 = 15

4 x - 4 = - 15 or 4 x - 4 = 15

x = - \frac{11}{4} or x = \frac{19}{4}

∣ 4 x - 4 ∣ = 11

- ∣ z - 6 ∣ + 2 = - 4

∣ 2 x + 1 ∣ = 6 x - 5

2 ∣ x ∣ - 3 = 8

∣ 3 x - 3 ∣ - 9 = 3
