|x|=14

Lösung

∣ x ∣ = 14

x = - 14 or x = 14

Schritte zur Lösung

∣ x ∣ = 14

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x = - 14 or x = 14

∣ 6 x - 9 ∣ < 9

\frac{x ^{2} - 16}{x ^{2} - 25} < 0

s im pl i f y \frac{9 ^{- 5}}{9 ^{3}}

3 y - 6 - 7 y = 12 - 4 y - 6

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