Lösung

∣ 4 - x ∣ = 1

x = 3 or x = 5

Schritte zur Lösung

∣ 4 - x ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 - x = - 1 or 4 - x = 1

4 - x = - 1 or 4 - x = 1

x = 3 or x = 5

- 3 ∣ x + 4 ∣ + 5 = - 7

∣ 3 x - 12 ∣ = x - 2

∣ x - 2 ∣ = 5 x + 10

∣ 6 - 6 x ∣ = 48

\frac{x}{3} = 4
