Schritte zur Lösung

∣ 9 x - 1 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 x - 1 = - 5 or 9 x - 1 = 5

9 x - 1 = - 5 or 9 x - 1 = 5

x = - \frac{4}{9} or x = \frac{2}{3}

12 - 8 ∣ k + 4 ∣ = - 4

∣ 6 x - 2 ∣ + 3 = 15

∣ b + 9 ∣ - 4 = - 12

∣ - 3 n + 22 ∣ = 5

∣ 5 - x ∣ - 10 = 0
