|r+8|=8

Lösung

∣ r + 8 ∣ = 8

r = - 16 or r = 0

Schritte zur Lösung

∣ r + 8 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

r + 8 = - 8 or r + 8 = 8

r + 8 = - 8 or r + 8 = 8

r = - 16 or r = 0

∣ 5 b + 9 ∣ + 16 = 2

∣ 3 + 10 x ∣ = 23

∣ x + 2 ∣ + 2 = 5 x

x^{2} - 9 = - 2 x + 6

- ∣ 2 x + 1 ∣ + 1 = 1
