Schritte zur Lösung

∣ 5 x + 2 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x + 2 = - 5 or 5 x + 2 = 5

5 x + 2 = - 5 or 5 x + 2 = 5

x = - \frac{7}{5} or x = \frac{3}{5}

∣ a ∣ = - 1

∣ 2 r - 10 ∣ + 3 = 5

∣ a ∣ - 16 = - 8

\frac{∣ x - 3 ∣}{3} = - 5

\frac{3 x - 1}{2} = 3
