Schritte zur Lösung

∣ - 4 d + 6 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 4 d + 6 = - 12 or - 4 d + 6 = 12

- 4 d + 6 = - 12 or - 4 d + 6 = 12

d = - \frac{3}{2} or d = \frac{9}{2}

4 - 2 ∣ 10 x - 1 ∣ = 11

∣ x - 3 ∣ + 9 = 5

∣ 1 - 4 x ∣ = 5

∣ 2 x - 1 ∣ = 4 x

5 ∣ x - 6 ∣ = 20
