|6u+3|=15

Lösung

∣ 6 u + 3 ∣ = 15

u = - 3 or u = 2

Schritte zur Lösung

∣ 6 u + 3 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

6 u + 3 = - 15 or 6 u + 3 = 15

6 u + 3 = - 15 or 6 u + 3 = 15

u = - 3 or u = 2

\frac{n}{9} = 5

\frac{n}{9} = 1

∣ 2 x - 3 ∣ - 4 = a x + b

∣ x + 1 ∣ + 7 = 5

3 = ∣ c - 5 ∣
