x, ∣ x - 2 ∣ = 4

x = - 2 or x = 6

Schritte zur Lösung

∣ x - 2 ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 2 = - 4 or x - 2 = 4

x - 2 = - 4 or x - 2 = 4

x = - 2 or x = 6

∣ - 10 + 3 x ∣ = 1313

∣ 3 x + 7 ∣ = x + 1

∣ 2 x + 2 ∣ - 3 = x - 2

so l v e f or x, ∣ x - 2 ∣ = x

7 - ∣ 2 x - 1 ∣ = 2
