|6+4x|=30

Lösung

∣ 6 + 4 x ∣ = 30

x = - 9 or x = 6

Schritte zur Lösung

∣ 6 + 4 x ∣ = 30

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

6 + 4 x = - 30 or 6 + 4 x = 30

6 + 4 x = - 30 or 6 + 4 x = 30

x = - 9 or x = 6

∣ 3 v - 9 ∣ = 3

∣ x - 2 ∣ = x - 2

(x - 1)^{2} + ∣ x - 1 ∣ - 2 = 0

4 = ∣ s ∣ - 3

∣ - x - 2 ∣ - 3 = 7
