Lösung

∣ 2 x - 2 ∣ = 6

x = - 2 or x = 4

Schritte zur Lösung

∣ 2 x - 2 ∣ = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 2 = - 6 or 2 x - 2 = 6

2 x - 2 = - 6 or 2 x - 2 = 6

x = - 2 or x = 4

∣ 4 x + 5 ∣ - 6 = 22

- 2 ∣ - 2 x - 4 ∣ = - 12

∣ x + 5 ∣ = 9

∣ x ∣ - 4 = 0

4 ∣ 2 x - 1 ∣ - 11 = - 6
