Lösung

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

x = - 14 or x = 11

Schritte zur Lösung

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

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{2 x + 3}{5} = - 5 or \frac{2 x + 3}{5} = 5

\frac{2 x + 3}{5} = - 5 or \frac{2 x + 3}{5} = 5

x = - 14 or x = 11

∣ x - 2 ∣ - 4 = 0

∣ x + 2 ∣ + 7 = 0

∣ x + 2 ∣ + 7 = 6

∣ x + 2 ∣ + 7 = 3

∣ 3 x - 4 ∣ + 8 = 13
