|-2r|=10

Lösung

∣ - 2 r ∣ = 10

r = - 5 or r = 5

Schritte zur Lösung

∣ - 2 r ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 r = - 10 or - 2 r = 10

- 2 r = - 10 or - 2 r = 10

r = - 5 or r = 5

\frac{∣ 16 - x ∣}{3} = 3 x

20 = 2 ∣ 2 k ∣

∣ - 2 r ∣ = 16

∣ x + 4 ∣ + 6 = 3

5 x^{2} - 8 ∣ x ∣ + 3 = 0
