Schritte zur Lösung

\frac{3 x + 4}{3} = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{3 x + 4}{3} = - 7 or \frac{3 x + 4}{3} = 7

\frac{3 x + 4}{3} = - 7 or \frac{3 x + 4}{3} = 7

x = - \frac{25}{3} or x = \frac{17}{3}

∣ x - 4 ∣ + ∣ x - 7 ∣ = 11

x ∣ x ∣ + 7 x - 8 = 0

2 ∣ (x - 2) (x - 5) ∣ = (x - 3)^{2}

∣ x + 3 ∣ = - ∣ x + 1 ∣

∣ 5 x + 16 ∣ = ∣ 3 x + 48 ∣
