Lösung

∣ 5 x + 10 ∣ = 15

x = - 5 or x = 1

Schritte zur Lösung

∣ 5 x + 10 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x + 10 = - 15 or 5 x + 10 = 15

5 x + 10 = - 15 or 5 x + 10 = 15

x = - 5 or x = 1

∣ x - 7 ∣ = 0

∣ 3 x - 4 ∣ = - 1

∣ 3 x ∣ = 1.5

∣ 3 v + 15 ∣ + 17 = 8

\frac{1}{2} x + 1 = 3
