Lösung

∣ 2 x - 4 ∣ = 22

x = - 9 or x = 13

Schritte zur Lösung

∣ 2 x - 4 ∣ = 22

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 4 = - 22 or 2 x - 4 = 22

2 x - 4 = - 22 or 2 x - 4 = 22

x = - 9 or x = 13

∣ y - 5 ∣ = 6

21 - 7 ∣ 2 x + 5 ∣ = - 14

∣ 3 - 2 x ∣ - ∣ x + 5 ∣ = - 3 x - 2

∣ 6 v + 24 ∣ = 0

- 7 + 2 ∣ - 2 x + 10 ∣ = 9
