x = - 8 or x = 4

Schritte zur Lösung

∣ 3 x + 6 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 6 = - 18 or 3 x + 6 = 18

3 x + 6 = - 18 or 3 x + 6 = 18

x = - 8 or x = 4

- 3 ∣ - 11 x ∣ = - 231

∣ 3 x + 6 ∣ = 6 x

\frac{x - 4}{5} = 9

6 - 6 ∣ 5 x - 5 ∣ = - 18

- 5 ∣ y ∣ = 0
