Lösung

∣ - 2 x ∣ = 12

x = - 6 or x = 6

Schritte zur Lösung

∣ - 2 x ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 x = - 12 or - 2 x = 12

- 2 x = - 12 or - 2 x = 12

x = - 6 or x = 6

∣ z - j ∣ = 4

4 - x^{2} = x^{2} - 4

7 = ∣ - 9 u ∣ + 7

∣ 4 x ∣ = x + 1

∣ d ∣ + 7 = 7
