Question

f(x9)= (3x-5)3

me ayudan ​

Answer 1

Respuesta:

$F\left(x\cdot \:9\right)=\left(3x-5\right)\cdot \:3\quad :\quad x=-\frac{5}{3\left(F-1\right)};\quad \:F\ne \:1$

Explicación paso a paso:

$9xF=9x-15$

$9xF-9x=9x-15-9x$

$9xF-9x=-15$

$9x\left(F-1\right)=-15$

$\frac{9x\left(F-1\right)}{9\left(F-1\right)}=\frac{-15}{9\left(F-1\right)};\quad \:F\ne \:1$

$x=-\frac{5}{3\left(F-1\right)};\quad \:F\ne \:1$

ESPERO QUE TE AYUDE :D
