|z-3|=1

Lösung

∣ z - 3 ∣ = 1

z = 2 or z = 4

Schritte zur Lösung

∣ z - 3 ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

z - 3 = - 1 or z - 3 = 1

z - 3 = - 1 or z - 3 = 1

z = 2 or z = 4

5 ∣ 2 x - 7 ∣ = 20

∣ 2 y + 10 ∣ = 12

∣ - 4 x ∣ = 3

∣ r - 6 ∣ = 32

∣ X + 5 ∣ - 3 = 1
