Schritte zur Lösung

∣ - 3 x + 4 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 3 x + 4 = - 7 or - 3 x + 4 = 7

- 3 x + 4 = - 7 or - 3 x + 4 = 7

x = - 1 or x = \frac{11}{3}

3 - 2 ∣ 3 x - 4 ∣ = 8 x - 3

∣ x - 1 ∣ - 6 = 5

∣ 5 x + 2 ∣ = 18

∣ 4 x - 8 ∣ + ∣ 2 - x ∣ = 5

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