Lösung

\frac{3 x - 9}{2} = 3

x = 1 or x = 5

Schritte zur Lösung

\frac{3 x - 9}{2} = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{3 x - 9}{2} = - 3 or \frac{3 x - 9}{2} = 3

\frac{3 x - 9}{2} = - 3 or \frac{3 x - 9}{2} = 3

x = 1 or x = 5

∣ 9 b - 6 ∣ - 4 = - 73

∣ 2 x - 7 ∣ = 0

∣ x + 2 ∣ = 4 - 3 x

∣ 6 - 2 x ∣ = - 3

5 ∣ x - 2 ∣ - 5 = 2
