x = - 16 or x = - 6

Schritte zur Lösung

∣ x + 11 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 11 = - 5 or x + 11 = 5

x + 11 = - 5 or x + 11 = 5

x = - 16 or x = - 6

2 ∣ 3 x + 9 ∣ + 1 = 3

∣ 9 x - 6 ∣ - 5 = - 5

5 ∣ 7 + b ∣ = 80

- ∣ c ∣ = - 47

∣ - 2 k ∣ = 14
