Schritte zur Lösung

∣ - 7 - 9 x ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 7 - 9 x = - 2 or - 7 - 9 x = 2

- 7 - 9 x = - 2 or - 7 - 9 x = 2

x = - 1 or x = - \frac{5}{9}

8 + ∣ 9 - 2 x ∣ = 11

∣ x ∣ + 3 = 0

20 = ∣ 1 - 3 c ∣

15 = ∣ b - 11 ∣

- ∣ 3 x - 7 ∣ + 7 = 4
