solvefor x,f(x)^{-1}=((4x-3))/((x+4))

Lösung

löse nach

x, f (x)^{- 1} = \frac{( 4 x - 3 )}{( x + 4 )}

Lösung

x = \frac{3 + f + f ^{2} + 70 f + 9}{8}, x = \frac{3 + f - f ^{2} + 70 f + 9}{8}

Schritte zur Lösung

f x^{- 1} = \frac{( 4 x - 3 )}{( x + 4 )}

Fasse zusammen

\frac{f}{x} = \frac{4 x - 3}{x + 4}

Kreuzmultiplizieren

f (x + 4) = x (4 x - 3)

Löse

f (x + 4) = x (4 x - 3) : x = \frac{3 + f + f ^{2} + 70 f + 9}{8}, x = \frac{3 + f - f ^{2} + 70 f + 9}{8}

x = \frac{3 + f + f ^{2} + 70 f + 9}{8}, x = \frac{3 + f - f ^{2} + 70 f + 9}{8}
