Schritte zur Lösung

∣ - 1 + 5 x ∣ = 11

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 1 + 5 x = - 11 or - 1 + 5 x = 11

- 1 + 5 x = - 11 or - 1 + 5 x = 11

x = - 2 or x = \frac{12}{5}

∣ 4 x + 1 ∣ = 17

∣ 4 x + 1 ∣ = 16

∣ 4 x + 1 ∣ = 13

∣ 4 x + 1 ∣ = 11

\frac{∣ - 4 - 3 x ∣}{4} = 2
