Lösung

∣ 5 x - 10 ∣ = 25

x = - 3 or x = 7

Schritte zur Lösung

∣ 5 x - 10 ∣ = 25

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x - 10 = - 25 or 5 x - 10 = 25

5 x - 10 = - 25 or 5 x - 10 = 25

x = - 3 or x = 7

4 ∣ 2 x + 1 ∣ = 3 x + 18

∣ 3 x + 1 ∣ = ∣ 0.3 x + 1 ∣

- 5 = 2 ∣ x ∣ - 6

∣ 3 x - 10 ∣ = 5

∣ 125 x - 34 ∣ = - 2
