Schritte zur Lösung

∣ 13 x + 4 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

13 x + 4 = - 3 or 13 x + 4 = 3

13 x + 4 = - 3 or 13 x + 4 = 3

x = - \frac{7}{13} or x = - \frac{1}{13}

3 - ∣ 2 x + 4 ∣ = 1

2 ∣ x - 1 ∣ = 6

∣ 3 x - 4 ∣ = 71

4 = 7 ∣ u ∣ - 8

∣ 5 x + 10 ∣ = 35
