Schritte zur Lösung

∣ - 3.5 x ∣ = 15.4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 3.5 x = - 15.4 or - 3.5 x = 15.4

- 3.5 x = - 15.4 or - 3.5 x = 15.4

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

10 = - 5 ∣ r ∣

5 - ∣ q ∣ = 0

∣ 7 x + 5 ∣ = 23

8 - 12 ∣ x + 5 ∣ = - 4

8 x + 8 = ∣ - 9 x + 4 ∣
