Lösung

∣ - 2 x - 6 ∣ = 8

x = - 7 or x = 1

Schritte zur Lösung

∣ - 2 x - 6 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 x - 6 = - 8 or - 2 x - 6 = 8

- 2 x - 6 = - 8 or - 2 x - 6 = 8

x = - 7 or x = 1

∣ t - 16 ∣ = 20

3 ∣ 5 x ∣ - 2 = 4

∣ 2 w + 1 ∣ = 5

∣ 5 x - 12 ∣ = 3

- 8 ∣ x - 3 ∣ + 2 = - 14
