∣ y + 840 ∣ = 40

y = - 880 or y = - 800

Schritte zur Lösung

∣ y + 840 ∣ = 40

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

y + 840 = - 40 or y + 840 = 40

y + 840 = - 40 or y + 840 = 40

y = - 880 or y = - 800

∣ 2 (x - 3) (x + 5) ∣ = 2

5 - ∣ 4 - x ∣ = - 2

x^{2} - 1 = x + 1

∣ j - 5 ∣ = j + 9

∣ 6 x - 2 ∣ = 0
