Lösung

∣ 5 y + 15 ∣ = 10

y = - 5 or y = - 1

Schritte zur Lösung

∣ 5 y + 15 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 y + 15 = - 10 or 5 y + 15 = 10

5 y + 15 = - 10 or 5 y + 15 = 10

y = - 5 or y = - 1

∣ 3 x - 3 ∣ + 4 = 2 x - 8

∣ y ∣ - 9 = 10

∣ 2 x + 6 ∣ = 3

4 - 9 ∣ - 6 - x ∣ = - 14

∣ 5 x + 15 ∣ = 45
