Lösung

∣ - 5 x - 15 ∣ = 35

x = - 10 or x = 4

Schritte zur Lösung

∣ - 5 x - 15 ∣ = 35

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 5 x - 15 = - 35 or - 5 x - 15 = 35

- 5 x - 15 = - 35 or - 5 x - 15 = 35

x = - 10 or x = 4

\frac{a}{b} - 3 ∣ a x ∣ = a

8 = ∣ y + 5 ∣

∣ 1 - 6 x ∣ = 6

∣ 2 x - 3 ∣ - x = 2

5 ∣ 2 Z + 7 ∣ = 20
