x = - 11 or x = 7

Schritte zur Lösung

∣ 2 x + 4 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = - 11 or x = 7

2 + 2 ∣ 2 x - 7 ∣ = 24

∣ 4 x + 1 ∣ + 1 = 3 x

∣ 3 x - 4 ∣ + 8 = x

∣ 5 x - 2 ∣ = 7 x + 14

∣ 3 x - 1 ∣ - 1 = x
