Lösung

∣ - 5 x ∣ = 30

x = - 6 or x = 6

Schritte zur Lösung

∣ - 5 x ∣ = 30

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 5 x = - 30 or - 5 x = 30

- 5 x = - 30 or - 5 x = 30

x = - 6 or x = 6

- 2 + ∣ 3 x - 3 ∣ = 25

∣ - 5 x ∣ = 35

5 ∣ x - 4 ∣ = - 35

∣ - 5 x ∣ = 20

\frac{∣ - 10 + a ∣}{4} = 5
