Lösung

∣ 2 x - 6 ∣ = 12

x = - 3 or x = 9

Schritte zur Lösung

∣ 2 x - 6 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 6 = - 12 or 2 x - 6 = 12

2 x - 6 = - 12 or 2 x - 6 = 12

x = - 3 or x = 9

∣ 10 z - 16 - 4 z ∣ = 8

4 ∣ x + 3 ∣ = 8 x - 12

∣ 3 x + 5 ∣ = 2 x + 2

\frac{∣ k + 7 ∣}{7} = 2

3 ∣ x + 3 ∣ - 6 = 0
