Schritte zur Lösung

∣ - 7 d - 8 ∣ = 71

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 7 d - 8 = - 71 or - 7 d - 8 = 71

- 7 d - 8 = - 71 or - 7 d - 8 = 71

d = - \frac{79}{7} or d = 9

so l v e f or y, ∣ x - 180 ∣ = 1.8 y + 90

so l v e f or x, ∣ 4 x + 5 ∣ - 4 = 20

15 = 5 ∣ 3 x + 3 ∣

- ∣ b - 4 ∣ = 24

∣ x - 1 ∣ ∣ - 6 ∣ = 5
