|-3+k|=1

Lösung

∣ - 3 + k ∣ = 1

k = 2 or k = 4

Schritte zur Lösung

∣ - 3 + k ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 3 + k = - 1 or - 3 + k = 1

- 3 + k = - 1 or - 3 + k = 1

k = 2 or k = 4

∣ x - 1 ∣ + 5 = - 2

∣ 4 r + 7 ∣ = 43

∣ - 6 x ∣ = 48

x^{2} - x - 2 = 2 x + 2

∣ x ∣ + 10 = 15
