Schritte zur Lösung

∣ 5 x - 4 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x - 4 = - 10 or 5 x - 4 = 10

5 x - 4 = - 10 or 5 x - 4 = 10

x = - \frac{6}{5} or x = \frac{14}{5}

6 ∣ c ∣ = 0

∣ 2 k - 1 ∣ = k

10 - ∣ 5 x ∣ = 4

15 = 2 - ∣ z + 4 ∣

8 - 8 \frac{a}{8} = - 1
