|-5-r|=3

Lösung

∣ - 5 - r ∣ = 3

r = - 8 or r = - 2

Schritte zur Lösung

∣ - 5 - r ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 5 - r = - 3 or - 5 - r = 3

- 5 - r = - 3 or - 5 - r = 3

r = - 8 or r = - 2

∣ 3 x - 1 ∣ = ∣ 5 x - 15 ∣

∣ 3 x - 9 ∣ = ∣ 2 x + 1 ∣

∣ 3 x - 1 ∣ + 4 = 1

∣ x - 3 ∣ = ∣ x - 2 ∣ + 1

2 ∣ 4 x - 2 ∣ - 3 = 1
