n(x)=((7x+5))/((x-9))

Lösung

n (x) = \frac{( 7 x + 5 )}{( x - 9 )}

x = \frac{9 n + 7 + 81 n ^{2} + 146 n + 49}{2 n}, x = \frac{9 n + 7 - 81 n ^{2} + 146 n + 49}{2 n}; n \neq = 0

n x (x - 9) = 7 x + 5 : x = \frac{9 n + 7 + 81 n ^{2} + 146 n + 49}{2 n}, x = \frac{9 n + 7 - 81 n ^{2} + 146 n + 49}{2 n}; n \neq = 0

x = \frac{9 n + 7 + 81 n ^{2} + 146 n + 49}{2 n}, x = \frac{9 n + 7 - 81 n ^{2} + 146 n + 49}{2 n}; n \neq = 0

\frac{x - 2}{x - 6} = \frac{- 4}{x}

\frac{1}{3 x} = 5

\frac{2 x - 3}{5 x} = \frac{11}{2}

\frac{14}{x} = \frac{7}{2}

\frac{8}{3 x} = \frac{1}{6}
