Schritte zur Lösung

∣ 5 x + 2 ∣ = 16

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x + 2 = - 16 or 5 x + 2 = 16

5 x + 2 = - 16 or 5 x + 2 = 16

x = - \frac{18}{5} or x = \frac{14}{5}

∣ 4 x + 2 ∣ = - 46

∣ y + 9 ∣ = 21

5 ∣ 2 x - 3 ∣ = 1

∣ x ∣ + x^{2} = 3 x

x^{2} - ∣ x ∣ + 1 = 0
