Schritte zur Lösung

∣ - 4 x - 5 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 4 x - 5 = - 7 or - 4 x - 5 = 7

- 4 x - 5 = - 7 or - 4 x - 5 = 7

x = - 3 or x = \frac{1}{2}

∣ x ∣ + 9 = - 15

∣ 2 g - 9 ∣ = 43

5 ∣ 3 - 12 x ∣ = 20

∣ 2 x - 4 ∣ = - 7

∣ x + 1 ∣ = 4 + 2 x
