Dezimale

x = - 2, x = 2.8

Schritte zur Lösung

∣ 5 x - 2 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x - 2 = - 12 or 5 x - 2 = 12

5 x - 2 = - 12 or 5 x - 2 = 12

x = - 2 or x = \frac{14}{5}

s im pl i f y \frac{1}{x} - \frac{1}{y}

9 x^{2} - 12 x - 4 = 0

x^{2} - 9 x = - 2 x - 6

s im pl i f y (5^{- 6})^{- 4}

6 + 6 x - 10 = - 20
