w, ∣ 3 w - 9 ∣ = 3

w = 2 or w = 4

Schritte zur Lösung

∣ 3 w - 9 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 w - 9 = - 3 or 3 w - 9 = 3

3 w - 9 = - 3 or 3 w - 9 = 3

w = 2 or w = 4

∣ c + 2 ∣ = 1

∣ 2 x ∣ - 2 = 2

- 2 ∣ 7 s ∣ = 0

2 ∣ 3 x ∣ - 8 = 10

2 = ∣ g + 3 ∣
