(5x}{x+7}=\frac{x+1)/2

Lösung

\frac{5 x}{x + 7} = \frac{x + 1}{2}

x = 1 + 6 i, x = 1 - 6 i

Schritte zur Lösung

\frac{5 x}{x + 7} = \frac{x + 1}{2}

Kreuzmultiplizieren

10 x = (x + 7) (x + 1)

Löse

10 x = (x + 7) (x + 1) : x = 1 + 6 i, x = 1 - 6 i

x = 1 + 6 i, x = 1 - 6 i

so l v e f or x, F = \frac{k}{x ^{2}}

\frac{5}{x + 3} = \frac{7}{2 x + 3}

\frac{3}{x} = \frac{4}{3}

\frac{2 x ^{2} + x - 15}{x + 3} = 4

\frac{2 x}{x - 1} + \frac{5}{2 x} = 2
