Lösung

∣ 2 x - 13 ∣ = 1

x = 6 or x = 7

Schritte zur Lösung

∣ 2 x - 13 ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 13 = - 1 or 2 x - 13 = 1

2 x - 13 = - 1 or 2 x - 13 = 1

x = 6 or x = 7

∣ 3 x - 1 ∣ = 2 x - 4

∣ x - 4 ∣ = 15

∣ m - 2 ∣ - 1 = 4

4 ∣ k ∣ + 4 = 16

∣ 4 x + 8 ∣ = 12
