|3u+6|=42

Lösung

∣ 3 u + 6 ∣ = 42

u = - 16 or u = 12

Schritte zur Lösung

∣ 3 u + 6 ∣ = 42

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 u + 6 = - 42 or 3 u + 6 = 42

3 u + 6 = - 42 or 3 u + 6 = 42

u = - 16 or u = 12

∣ 2 x - 3 ∣ = \frac{x}{5}

- ∣ 12 - 2 x ∣ = - 7

∣ x - 3 ∣ + 4 x = 1 + x

∣ 2 + x ∣ = 1

\frac{∣ 6 x + 9 ∣}{3} = 5
