3/(x+1)= x/(x-1)

Lösung

\frac{3}{x + 1} = \frac{x}{x - 1}

x = 1 + 2 i, x = 1 - 2 i

Schritte zur Lösung

Kreuzmultiplizieren

3 (x - 1) = (x + 1) x

Löse

3 (x - 1) = (x + 1) x : x = 1 + 2 i, x = 1 - 2 i

x = 1 + 2 i, x = 1 - 2 i

a + \frac{1}{a} = 10

\frac{2 x - 4}{x - 2} = - 7

\frac{2}{10} = \frac{4}{a - 3}

1 = \frac{14 x ^{2}}{x ^{4} + 49}
