Schritte zur Lösung

∣ 4 - 5 x ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = 0 or x = \frac{8}{5}

- 10 + 5 ∣ 9 - 4 x ∣ = 115

∣ 0.2 x + 5 ∣ = x^{2} - 2

3 ∣ 3 (x + 5) (x - 1) ∣ + 5 = 32

- 5 ∣ 6 - h ∣ + 7 = - 13

- ∣ - x ∣ = - 9
