n(x)=((7x+8))/((x-5))

Lösung

n (x) = \frac{( 7 x + 8 )}{( x - 5 )}

x = \frac{5 n + 7 + 25 n ^{2} + 102 n + 49}{2 n}, x = \frac{5 n + 7 - 25 n ^{2} + 102 n + 49}{2 n}; n \neq = 0

Schritte zur Lösung

n (x) = \frac{( 7 x + 8 )}{( x - 5 )}

Vereinfache

\frac{( 7 x + 8 )}{( x - 5 )} : \frac{7 x + 8}{x - 5}

n (x) = \frac{7 x + 8}{x - 5}

Löse

n x (x - 5) = 7 x + 8 : x = \frac{5 n + 7 + 25 n ^{2} + 102 n + 49}{2 n}, x = \frac{5 n + 7 - 25 n ^{2} + 102 n + 49}{2 n}; n \neq = 0

x = \frac{5 n + 7 + 25 n ^{2} + 102 n + 49}{2 n}, x = \frac{5 n + 7 - 25 n ^{2} + 102 n + 49}{2 n}; n \neq = 0

\frac{8}{x} = \frac{2}{3}

\frac{2 x ^{2} + 6 x - 8}{x + 4} = 0

so l v e f or y, x = \frac{1}{y} - 2

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

\frac{2 x - 6}{x} = \frac{x - 3}{3}
