Schritte zur Lösung

∣ 3 x + 2 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 2 = - 8 or 3 x + 2 = 8

3 x + 2 = - 8 or 3 x + 2 = 8

x = - \frac{10}{3} or x = 2

2 ∣ 4 x - 5 ∣ - 8 = - 6

∣ x - 2 ∣ = 3 x

5 + ∣ x - 2 ∣ = 7

∣ 0.5 x + 3 ∣ = x^{2} - 4

∣ x + 4 ∣ = - 7
