∣ x - 4 ∣ = \frac{12}{5}

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 4 = - \frac{12}{5} or x - 4 = \frac{12}{5}

x - 4 = - \frac{12}{5} or x - 4 = \frac{12}{5}

x = \frac{8}{5} or x = \frac{32}{5}

- ∣ x - 2 ∣ = 0

5 ∣ 6 x + 7 ∣ + 4 = 29

∣ - 3 x + 6 ∣ - 5 = 13

∣ 3 x + 9 ∣ = 30

∣ 2 - 2 t ∣ + 6 = 12
