| n/(10)|=2

Lösung

\frac{n}{10} = 2

n = - 20 or n = 20

Schritte zur Lösung

\frac{n}{10} = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{n}{10} = - 2 or \frac{n}{10} = 2

\frac{n}{10} = - 2 or \frac{n}{10} = 2

n = - 20 or n = 20

j (x) = - ∣ 4 x ∣ - 1

∣ 4 x - 3 ∣ - 4 = 0

4 ∣ 3 x - 2 ∣ = 40

∣ x - 8 ∣ = 0

∣ x + 2 ∣ - 3 = 4
