Answer:

\sf\leadsto -\dfrac{3}{4}

\small\underline\frak{we\: have, }

\leadsto\sf \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \frac{15}{4}  - 7x = 9

\huge\underline\textsf{Explantion:- }

\underbrace{\red{\sf{ Transposing \:</p><p>  \dfrac{15}{4}  \:  to \: RHS }}}

\leadsto\sf- 7x =  \frac{21}{4}  \\

\leadsto\sf x =  \frac{21}{4 \times ( - 7)}  \\

\underbrace{\red{\sf{dividing \:both\: side \:by -7}}}

\leadsto\sf x =  \frac{3 \times 7}{4 \times 7} \\

\leadsto\sf x =  -  \frac{3}{4}  \\

\huge\underline\textsf{Verification:- }

\implies\sf \frac{15}{4}  - 7( \frac{ - 3}{4} ) \\

\implies\sf \frac{15}{4}  +  \frac{21}{4}  \\

\implies\sf \frac{\cancel{36}}{\cancel4} \\

\implies\sf 9 =  \: rhs
