Schritte zur Lösung

∣ 9 x + 4 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 x + 4 = - 8 or 9 x + 4 = 8

9 x + 4 = - 8 or 9 x + 4 = 8

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

∣ 2 x - 1 ∣ - 2 = 15

∣ 4 x + 3 ∣ - 9 = - 5

∣ 8 + 5 x ∣ = - x + 7

- 7 ∣ 10 x - 3 ∣ - 4 = - 25

∣ 7 s ∣ = 0
