x = - 6 or x = - 4

Schritte zur Lösung

∣ 3 x + 15 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 15 = - 3 or 3 x + 15 = 3

3 x + 15 = - 3 or 3 x + 15 = 3

x = - 6 or x = - 4

∣ 6 x + 4 ∣ = 8

∣ 3 m + 2 ∣ = 1

∣ 2 x + 4 ∣ = 3 x - 1

∣ 7 x - 7 ∣ = 21

- 4 + 8 ∣ n - 10 ∣ = 52
