|u+675|=125

Lösung

∣ u + 675 ∣ = 125

u = - 800 or u = - 550

Schritte zur Lösung

∣ u + 675 ∣ = 125

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

u + 675 = - 125 or u + 675 = 125

u + 675 = - 125 or u + 675 = 125

u = - 800 or u = - 550

3 ∣ 9 x - 3 ∣ = 6

5 ∣ 3 x - 7 ∣ = 15

15 = ∣ d ∣ - 3

∣ 5 x + 3 ∣ + 2 x - 7 = 21

5 ∣ 3 x - 7 ∣ = 10
