|2x-4|=16

Lösung

∣ 2 x - 4 ∣ = 16

x = - 6 or x = 10

Schritte zur Lösung

∣ 2 x - 4 ∣ = 16

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 4 = - 16 or 2 x - 4 = 16

2 x - 4 = - 16 or 2 x - 4 = 16

x = - 6 or x = 10

∣ 2 x - 4 ∣ = 18

∣ 2 x - 4 ∣ = 20

5 - ∣ 3 x + 6 ∣ = 2

- 4 ∣ U + 5 ∣ = - 40

x ∣ x + 4 ∣ + 8 = 4
