Schritte zur Lösung

∣ 3 x + 5 ∣ = 0

Wende Absoluteregel an: Wenn

∣ u ∣ = 0

dann

u = 0

3 x + 5 = 0

3 x + 5 = 0 : x = - \frac{5}{3}

x = - \frac{5}{3}

∣ x + 1 ∣ + ∣ x - 2 ∣ = 3 x - 4

∣ 4 - 2 x ∣ + ∣ x + 7 ∣ = 30

so l v e f or a, ∣ a - b ∣ = \frac{∣ b ∣}{2}

∣ x ∣ + ∣ x - 2 ∣ = 0

∣ x ∣ + ∣ x - 2 ∣ = 4
