x, \frac{x}{5} = 3

x = - 15 or x = 15

Schritte zur Lösung

\frac{x}{5} = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = - 15 or x = 15

∣ x + 1 ∣ - 3 = - x

∣ 2 x ∣ + 8 = 24

4 - 6 ∣ 3 - 5 a ∣ = - 104

- 2 ∣ 7 - 3 b ∣ - 6 = - 6

6 ∣ y ∣ = 24
