Schritte zur Lösung

∣ - 3.5 d ∣ = 15.4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 3.5 d = - 15.4 or - 3.5 d = 15.4

- 3.5 d = - 15.4 or - 3.5 d = 15.4

d = - \frac{22}{5} or d = \frac{22}{5}

∣ x - 2 ∣ + 5 = 9

8 z + 20 = - ∣ 2 z + 4 ∣

∣ 7 x + 4 ∣ + 5 = 0

∣ x ∣ = - 4

∣ x - 10 ∣ = x^{2} - 10 x
