x = - 6 or x = 14

Schritte zur Lösung

∣ - 2 x + 8 ∣ = 20

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 x + 8 = - 20 or - 2 x + 8 = 20

- 2 x + 8 = - 20 or - 2 x + 8 = 20

x = - 6 or x = 14

- 3 ∣ 1 - 23 v ∣ = - 9

4 - 3 ∣ q ∣ = 10

∣ 2 x - 1 ∣ = - 9

∣ 5 x - 4 ∣ = - 6

∣ 1 - 5 x ∣ = 16
