Lösung

∣ 4 x + 8 ∣ = 12

x = - 5 or x = 1

Schritte zur Lösung

∣ 4 x + 8 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x + 8 = - 12 or 4 x + 8 = 12

4 x + 8 = - 12 or 4 x + 8 = 12

x = - 5 or x = 1

\frac{1}{2} x + 5 = 3

\frac{x}{5} = 1

3 ∣ 2 x + 2 ∣ - 2 x = x + 3

5 ∣ x - 4 ∣ - 5 = 2

∣ 3 x - 4 ∣ = 11
