x = 6 or x = 12

Schritte zur Lösung

∣ - 9 + x ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 9 + x = - 3 or - 9 + x = 3

- 9 + x = - 3 or - 9 + x = 3

x = 6 or x = 12

∣ x + 3 ∣ = 3^{x} + 1

3 ∣ 2 x - 4 ∣ = 0

7 = - 4 ∣ 8 p + 7 ∣ - 1

∣ 4 x - 12 ∣ - 3 = 9

∣ x + 2 ∣ = - 5
