Lösung

∣ 2 x - 2 ∣ = 10

x = - 4 or x = 6

Schritte zur Lösung

∣ 2 x - 2 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 2 = - 10 or 2 x - 2 = 10

2 x - 2 = - 10 or 2 x - 2 = 10

x = - 4 or x = 6

4 ∣ 4 - 8 x ∣ = 20

∣ x - 5 ∣ = 2 x - 3

∣ x + 3 ∣ = 2 x - 2

∣ x + 3 ∣ = 2 x - 1

∣ x + 6 ∣ + 9 = 2
