Lösung

∣ 4 x + 2 ∣ = 18

x = - 5 or x = 4

Schritte zur Lösung

∣ 4 x + 2 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x + 2 = - 18 or 4 x + 2 = 18

4 x + 2 = - 18 or 4 x + 2 = 18

x = - 5 or x = 4

∣ - 6 x ∣ = 24

6 x^{2} - x - 1 = 5 - x

∣ 3 x - 1 ∣ + 2 = 8

5 ∣ 2 x ∣ - 4 = 26

∣ - 3 x + 6 ∣ = 15
