Lösung

∣ d - 3 ∣ = 5

d = - 2 or d = 8

Schritte zur Lösung

∣ d - 3 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

d - 3 = - 5 or d - 3 = 5

d - 3 = - 5 or d - 3 = 5

d = - 2 or d = 8

∣ 6 y + 9 ∣ = 8

- 2 ∣ - 2 k + 1 ∣ = - 18

1 = ∣ 5 x + 9 ∣ + 6

∣ 4 x + 6 ∣ - 4 x = - 10

∣ 13 + 4 y ∣ = 13
