|14-2x|=20

Lösung

∣ 14 - 2 x ∣ = 20

x = - 3 or x = 17

Schritte zur Lösung

∣ 14 - 2 x ∣ = 20

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

14 - 2 x = - 20 or 14 - 2 x = 20

14 - 2 x = - 20 or 14 - 2 x = 20

x = - 3 or x = 17

∣ 4 x - 22 ∣ - 5 = - 3

∣ x (4 - x) + 4 ∣ = 0

∣ 4 x - 8 ∣ = 32

3 ∣ x + 5 ∣ - 2 = 7

∣ x + 2 ∣ = 3 x
