Lösung

löse nach

x, ∣ 8 - 2 x ∣ = 16

x = - 4 or x = 12

Schritte zur Lösung

∣ 8 - 2 x ∣ = 16

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

8 - 2 x = - 16 or 8 - 2 x = 16

8 - 2 x = - 16 or 8 - 2 x = 16

x = - 4 or x = 12

∣ 3 x ∣ + 6 + 4 = 25

x^{2} - 3 x = 0

∣ x - 6 ∣ = 3 x

∣ 3 g ∣ - 4 = 11

∣ x - 3 ∣ = 2 x + 4
