Schritte zur Lösung

\frac{- 7 x + 2}{5} = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{- 7 x + 2}{5} = - 4 or \frac{- 7 x + 2}{5} = 4

\frac{- 7 x + 2}{5} = - 4 or \frac{- 7 x + 2}{5} = 4

x = - \frac{18}{7} or x = \frac{22}{7}

∣ 4 x + 2 ∣ + 2 = 6

∣ 2 x - 3 ∣ = 20

- 2 ∣ - 3 x + 2 ∣ = - 4

3 ∣ x - 6 ∣ = 4

- 2 ∣ x - 3 ∣ = 0
