x = 4 or x = 20

Schritte zur Lösung

∣ x - 12 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 12 = - 8 or x - 12 = 8

x - 12 = - 8 or x - 12 = 8

x = 4 or x = 20

∣ 5 x - 3 ∣ = 2 x + 3

∣ 3 y ∣ - 5 = - 23

∣ 6 n ∣ = 6

∣ 3 x - 1 ∣ = x + 1

- 2 ∣ 4 n + 16 ∣ + 3 = - 21
