Schritte zur Lösung

∣ - 3 x - 8 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 3 x - 8 = - 10 or - 3 x - 8 = 10

- 3 x - 8 = - 10 or - 3 x - 8 = 10

x = - 6 or x = \frac{2}{3}

∣ 2 b - 5 ∣ = 7

∣ 3 m - 2 ∣ = 2 m - 3

∣ 4 x + 7 ∣ - 6 = 14

- 3 ∣ 5 x + 1 ∣ - 6 = - 9

2 x^{2} = ∣ x - 1 ∣
