Schritte zur Lösung

∣ 4 z + 16 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 z + 16 = - 2 or 4 z + 16 = 2

4 z + 16 = - 2 or 4 z + 16 = 2

z = - \frac{9}{2} or z = - \frac{7}{2}

8 ∣ - 5 + a ∣ - 2 = 102

∣ x + 2 ∣ = 16

∣ x + 2 ∣ = 11

∣ 1 - 3 t ∣ + 4 = 1

∣ - 5 c + 1 ∣ = 77
