Lösung

∣ 6 x - 6 ∣ = 18

x = - 2 or x = 4

Schritte zur Lösung

∣ 6 x - 6 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

6 x - 6 = - 18 or 6 x - 6 = 18

6 x - 6 = - 18 or 6 x - 6 = 18

x = - 2 or x = 4

2 = ∣ u ∣ - 6

8 = 2 + ∣ x - 4 ∣

2 x - 1 + ∣ 2 x - 1 ∣ = 0

4 \frac{x}{3} - 5 = 3

21 ∣ 5 - 12 x ∣ = 7
