Lösung

∣ 4 x - 4 ∣ = 12

x = - 2 or x = 4

Schritte zur Lösung

∣ 4 x - 4 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x - 4 = - 12 or 4 x - 4 = 12

4 x - 4 = - 12 or 4 x - 4 = 12

x = - 2 or x = 4

\frac{x}{4} = 2

\frac{- 4 - 3 x}{4} = 2

14 - ∣ 3 k + 6 ∣ = 5

∣ x - 5 ∣ = 4 x + 1

1 + 9 ∣ - 5 x - 1 ∣ = - 8
