nikdorinn [45]

\huge\mathfrak\blue{answer}

= q -  \frac{q91}{2}  =  \frac{k}{9}

\blue{switch \: sides}

= \frac{k}{9}  = q -  \frac{q91}{2}

\blue{multiply \: 9 \: both \: sides}

=  \frac{9k}{9}  = 9q - 9 \: . \:  \frac{q91}{2}

\blue{lastly \: simplify}

=\underline {k = 9q -  \frac{{9q}^{91} }{2} }
