x = - 1 or x = 1

Schritte zur Lösung

∣ - 2 x ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 x = - 2 or - 2 x = 2

- 2 x = - 2 or - 2 x = 2

x = - 1 or x = 1

∣ - 2 x + 8 ∣ + 6 = 1

∣ x - 5 ∣ + 4 = 9

- 3 ∣ 6 k + 1 ∣ + 1 = - 86

5 \frac{1}{2} r + 3 = 5

6 ∣ - 4 x - 5 ∣ - 12 = 30
