|2v-4|=10

Lösung

∣ 2 v - 4 ∣ = 10

v = - 3 or v = 7

Schritte zur Lösung

∣ 2 v - 4 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 v - 4 = - 10 or 2 v - 4 = 10

2 v - 4 = - 10 or 2 v - 4 = 10

v = - 3 or v = 7

∣ x - 2 ∣ = ∣ x ∣

\frac{∣ 4 x + 5 ∣ + 8}{5} = 3

∣ 2 y + 5 ∣ - 3 = 0

∣ y - 6 ∣ + 3 = 3 y

∣ 3 x - 2 ∣ = 2 x + 1
