Schritte zur Lösung

∣ 3 x + 2 ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x + 2 = - 9 or 3 x + 2 = 9

3 x + 2 = - 9 or 3 x + 2 = 9

x = - \frac{11}{3} or x = \frac{7}{3}

∣ 8 x ∣ - 5 = 75

(2 + ∣ x - 2 ∣) = 1

- x + ∣ 2 x - 7 ∣ = 4

2 ∣ 3 x - 6 ∣ = 18

2 - 2 ∣ 5 x - 2 ∣ = - 18 - 18
