|3z-3|=9

Lösung

∣ 3 z - 3 ∣ = 9

z = - 2 or z = 4

Schritte zur Lösung

∣ 3 z - 3 ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 z - 3 = - 9 or 3 z - 3 = 9

3 z - 3 = - 9 or 3 z - 3 = 9

z = - 2 or z = 4

∣ u ∣ = - 3

2 ∣ 24 - 6 x ∣ - 16 = - 4

∣ - 4 x + 2 ∣ = 8 x + 6

- 10 = ∣ x ∣ - 12

∣ x - 4 ∣ = 4 - x
