|80-8b|=80

Lösung

∣ 80 - 8 b ∣ = 80

b = 0 or b = 20

Schritte zur Lösung

∣ 80 - 8 b ∣ = 80

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

80 - 8 b = - 80 or 80 - 8 b = 80

80 - 8 b = - 80 or 80 - 8 b = 80

b = 0 or b = 20

∣ x - 3 ∣ - 13 = - 4

9 = ∣ - 2 t ∣ + 1

∣ x + 4.5 ∣ = 10.5

\frac{2 x - 4}{3} = 2

so l v e f or x, 3 ∣ x - 6 ∣ = 8
