|u+620|=25

Lösung

∣ u + 620 ∣ = 25

u = - 645 or u = - 595

Schritte zur Lösung

∣ u + 620 ∣ = 25

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

u + 620 = - 25 or u + 620 = 25

u + 620 = - 25 or u + 620 = 25

u = - 645 or u = - 595

∣ - 4 - 7 n ∣ = 45

- 5 ∣ 4 + 5 x ∣ + 3 = 13

- 6 ∣ n ∣ = 0

∣ 3 x + 4 ∣ + 8 = 7

∣ 3 - 3 t ∣ + 5 = 14
