x/(2a)=(4a)/(x+2a)

Lösung

\frac{x}{2 a} = \frac{4 a}{x + 2 a}

x = 2 a, x = - 4 a; a \neq = 0

Schritte zur Lösung

\frac{x}{2 a} = \frac{4 a}{x + 2 a}

Kreuzmultiplizieren

x (x + 2 a) = 8 a^{2}; a \neq = 0

Löse

x (x + 2 a) = 8 a^{2} : x = 2 a, x = - 4 a

x = 2 a, x = - 4 a; a \neq = 0

\frac{1}{x - 2} + 5 = \frac{21}{x - 2}

\frac{x ^{2}}{x ^{2} - 1} = 0

\frac{4 ( x - 2 )}{x - 3} = 3

so l v e f or y, \frac{y + 1}{y - 1} = x

\frac{x}{2 x - 4} - 7 = \frac{1}{x - 2}
