y = - 7 or y = 29

Schritte zur Lösung

∣ y - 11 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

y - 11 = - 18 or y - 11 = 18

y - 11 = - 18 or y - 11 = 18

y = - 7 or y = 29

∣ - 2 b + 11 ∣ = 17

3 ∣ 2 x + 5 ∣ = 9 x - 6

∣ a + 10 ∣ = 34

∣ b + 18 ∣ = 50

∣ - 4 x + 4 ∣ = 12
