∣ x - 9 ∣ = 6

x = 3 or x = 15

Schritte zur Lösung

∣ x - 9 ∣ = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 9 = - 6 or x - 9 = 6

x - 9 = - 6 or x - 9 = 6

x = 3 or x = 15

∣ 9 x + 1 ∣ = 73

6 + 4 ∣ x + 1 ∣ = 6

- 4 - ∣ x - 2 ∣ = - 12

∣ 7 - x ∣ = 15

∣ x - 8 ∣ - 4 = - 1
