∣ y + 4 ∣ = 8

y = - 12 or y = 4

Schritte zur Lösung

∣ y + 4 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

y + 4 = - 8 or y + 4 = 8

y + 4 = - 8 or y + 4 = 8

y = - 12 or y = 4

\frac{1}{3} ∣ 3 x + 8 ∣ + 4 = 8

∣ 2 x - 4 ∣ = 22

∣ y - 5 ∣ = 6

21 - 7 ∣ 2 x + 5 ∣ = - 14

∣ 3 - 2 x ∣ - ∣ x + 5 ∣ = - 3 x - 2
