∣ 3 x - 1 ∣ = 3

x = - \frac{2}{3} or x = \frac{4}{3}

Dezimale

x = - 0.66666 \dots, x = 1.33333 \dots

Schritte zur Lösung

∣ 3 x - 1 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x - 1 = - 3 or 3 x - 1 = 3

3 x - 1 = - 3 or 3 x - 1 = 3

x = - \frac{2}{3} or x = \frac{4}{3}

\frac{1}{x} \leq \frac{1}{2}

\frac{3 - 2 x}{5} - 3 < 6

s im pl i f y - ln (\frac{2}{2})

\frac{4 x + 7}{x - 1} < 3

s im pl i f y \frac{- 4 + i}{i}
