Lösung

∣ 3 x + 3 ∣ = 15

x = - 6 or x = 4

Schritte zur Lösung

∣ 3 x + 3 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 3 = - 15 or 3 x + 3 = 15

3 x + 3 = - 15 or 3 x + 3 = 15

x = - 6 or x = 4

∣ 2 x - 1 ∣ = 3 x

x^{2} = 2 ∣ x + 2 ∣ - 2 x

3 ∣ x ∣ + 2 = 11

2 ∣ 3 x - 3 ∣ - 4 = 12

∣ 9 + 3 n ∣ = 12
