Lösung

∣ 2 x - 8 ∣ = 10

x = - 1 or x = 9

Schritte zur Lösung

∣ 2 x - 8 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 8 = - 10 or 2 x - 8 = 10

2 x - 8 = - 10 or 2 x - 8 = 10

x = - 1 or x = 9

∣ 7 - 2 x ∣ + 4 = 5

∣ x - 4 ∣ = x + 2

1 - ∣ 4 x + 5 ∣ = - 2

3 + 4 ∣ 1 - 2 x ∣ = 11

- ∣ 3 + x ∣ = c
