Schritte zur Lösung

∣ 4 x + 4 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x + 4 = - 15 or 4 x + 4 = 15

4 x + 4 = - 15 or 4 x + 4 = 15

x = - \frac{19}{4} or x = \frac{11}{4}

∣ c + 380 ∣ = 15

∣ - 5 x + 12 ∣ = - 2 x + 1

∣ b + 8 ∣ + 4 = 5

30 = ∣ 10 + 4 c ∣

∣ x + 8 ∣ + 6 = 4 x - 10
