Lösung

∣ 2 x + 6 ∣ = 8

x = - 7 or x = 1

Schritte zur Lösung

∣ 2 x + 6 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x + 6 = - 8 or 2 x + 6 = 8

2 x + 6 = - 8 or 2 x + 6 = 8

x = - 7 or x = 1

4 ∣ x ∣ - 1 = 15

∣ x ∣ - 11 = 26

∣ x - 1 ∣ + ∣ 2 x - 1 ∣ = 6

∣ x - 3 ∣ + ∣ x - 6 ∣ = 5

8 - ∣ 1 - 2 x ∣ = x
