Schritte zur Lösung

∣ - 2 (x + 2) ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 (x + 2) = - 1 or - 2 (x + 2) = 1

- 2 (x + 2) = - 1 or - 2 (x + 2) = 1

x = - \frac{5}{2} or x = - \frac{3}{2}

∣ - 14 y + 4 ∣ + 7 = 2

∣ 8 x + 2 ∣ + 3 = 6

∣ x + 5 ∣ = 4 x + 8

4 ∣ 3 t + 8 ∣ = 16 t

∣ 4 f + 1 ∣ - 2 = 5
