Schritte zur Lösung

∣ 3 - 5 x ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 - 5 x = - 4 or 3 - 5 x = 4

3 - 5 x = - 4 or 3 - 5 x = 4

x = - \frac{1}{5} or x = \frac{7}{5}

5 ∣ 2 x + 6 ∣ = 25

∣ 2 x - 5 ∣ = 5

∣ - 2 x + 10 ∣ = 30

∣ 2 x + 5 ∣ + 4 = 3

- ∣ x ∣ = ∣ x ∣
