Schritte zur Lösung

∣ 3 + 7 x ∣ = 73

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 + 7 x = - 73 or 3 + 7 x = 73

3 + 7 x = - 73 or 3 + 7 x = 73

x = - \frac{76}{7} or x = 10

x \cdot ∣ x - 3 ∣ - 2 = 0

∣ 7 x - 12 ∣ = ∣ 4 - 3 x ∣

\frac{h}{8} = 4

2 ∣ 8 x + 4 ∣ = - 24

∣ 2 d ∣ + 3 = 21
