Schritte zur Lösung

∣ 4 x + 1 ∣ = 16

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x + 1 = - 16 or 4 x + 1 = 16

4 x + 1 = - 16 or 4 x + 1 = 16

x = - \frac{17}{4} or x = \frac{15}{4}

∣ 4 x + 1 ∣ = 13

∣ 4 x + 1 ∣ = 11

\frac{∣ - 4 - 3 x ∣}{4} = 2

∣ 7 t + 8 ∣ + 7 = 10

∣ 5 x + 8 ∣ = 0
