k = - 17 or k = 7

Schritte zur Lösung

∣ k + 5 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

k + 5 = - 12 or k + 5 = 12

k + 5 = - 12 or k + 5 = 12

k = - 17 or k = 7

∣ 2 k + 1 ∣ = 9

∣ 6 n - 6 ∣ = - 72

5 ∣ x + 6 ∣ = 15 x - 10

- 5 ∣ 5 x + 3 ∣ + 28 = 18

∣ x + π ∣ = x^{2} + 1
