Schritte zur Lösung

\frac{4}{5} - 2 x = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{4}{5} - 2 x = - 4 or \frac{4}{5} - 2 x = 4

\frac{4}{5} - 2 x = - 4 or \frac{4}{5} - 2 x = 4

x = - \frac{8}{5} or x = \frac{12}{5}

8 ∣ - 5 p ∣ - 7 = - 15

∣ 2 x + 5 ∣ + 4 x = 3

∣ 4 x - 5 ∣ = 5 x - 4

2 ∣ x + 5 ∣ = - 4

5 - 7 ∣ 5 - x ∣ = - 44
