Lösung

∣ k + 6 ∣ = 9

k = - 15 or k = 3

Schritte zur Lösung

∣ k + 6 ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

k + 6 = - 9 or k + 6 = 9

k + 6 = - 9 or k + 6 = 9

k = - 15 or k = 3

3 ∣ x - 6 ∣ = 16

∣ 3 - 5 x ∣ = 7

∣ 3 x - 11 ∣ = x + 3

∣ x - 8 ∣ = 14

- 3 ∣ 9 x - 7 ∣ = 2
