x, ∣ 2 x - 1 ∣ = 5

x = - 2 or x = 3

Schritte zur Lösung

∣ 2 x - 1 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 1 = - 5 or 2 x - 1 = 5

2 x - 1 = - 5 or 2 x - 1 = 5

x = - 2 or x = 3

∣ 9 x - 49 ∣ = - 41

- ∣ 2 x + 1 ∣ = 0

∣ 3 - x ∣ = x

∣ x - 4 ∣ + 5 = 2

∣ 4 n + 7 ∣ = 1
