∣ - 3 x ∣ = 18

x = - 6 or x = 6

Schritte zur Lösung

∣ - 3 x ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 3 x = - 18 or - 3 x = 18

- 3 x = - 18 or - 3 x = 18

x = - 6 or x = 6

s im pl i f y 6 - (- 4)

\frac{x}{x + 2} - \frac{5}{x - 4} < 0

5 x^{2} - 9 x = 2

s im pl i f y \frac{3}{10} \cdot \frac{2}{5}

- 4 x - 7 + 10 x = - 7 + 6 x
