Lösung

∣ 8 - 4 x ∣ = 40

x = - 8 or x = 12

Schritte zur Lösung

∣ 8 - 4 x ∣ = 40

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

8 - 4 x = - 40 or 8 - 4 x = 40

8 - 4 x = - 40 or 8 - 4 x = 40

x = - 8 or x = 12

6 x + 4 = ∣ x - 8 ∣

3 ∣ 4 x + 6 ∣ = 24

- 2 ∣ x + 4 ∣ = - 1

∣ 2 x - 4 ∣ = 5

∣ x + 3 ∣ + 2.5 = 3
