Schritte zur Lösung

∣ 15 \cdot 9 x ∣ = 48

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

15 \cdot 9 x = - 48 or 15 \cdot 9 x = 48

15 \cdot 9 x = - 48 or 15 \cdot 9 x = 48

x = - \frac{16}{45} or x = \frac{16}{45}

- 8 = - 2 ∣ c ∣

5 x - 2 - ∣ 4 x - 3 ∣ = 1 - x

∣ 8 x - 6 ∣ = 6

∣ x + 2 ∣ = 2 x

9 ∣ x - 6 ∣ - 9 = - 2
