|3u-6|=42

Lösung

∣ 3 u - 6 ∣ = 42

u = - 12 or u = 16

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 = - 12 or u = 16

3 ∣ c - 6 ∣ - 10 = - 31

∣ x + 7 ∣ + 2 = 4 x

∣ 2 x + 10 ∣ - 5 = 3 x

∣ b ∣ = \frac{2}{3}

∣ 2 k + 3 ∣ = 7
