\frac{x - 4}{5} = 9

x = - 41 or x = 49

Schritte zur Lösung

\frac{x - 4}{5} = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{x - 4}{5} = - 9 or \frac{x - 4}{5} = 9

\frac{x - 4}{5} = - 9 or \frac{x - 4}{5} = 9

x = - 41 or x = 49

6 - 6 ∣ 5 x - 5 ∣ = - 18

- 5 ∣ y ∣ = 0

4 ∣ 2 x + 7 ∣ + 12 = 5

- 12 ∣ 4 x - 2 ∣ + 7 = 15

x^{2} + 5 = 0
