|x|=9

Lösung

∣ x ∣ = 9

x = - 9 or x = 9

Schritte zur Lösung

∣ x ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x = - 9 or x = 9

(x - 5)^{2} = 5

s im pl i f y - \frac{9}{15}

s im pl i f y \frac{y ^{2}}{y ^{9}}

(\frac{7}{8}) (\frac{4}{5}) (\frac{4}{7} - \frac{3}{14})

0 = x - 3 \cdot 16.1
