$\color{red}{QUESTION}$

Solve: $\frac{15}{4} - 7x = 9$

To find: $x$

$\color{blue}{ANSWER}$

=> $\frac{15}{4} - 7x = 9$

=> $\frac{15}{4} - 9 = 7x$

=> $\frac{15}{4} - \frac{3}{4} = 7x$

=> $\frac{15 - 36}{4} = 7x$

=> $\frac{ - 21}{4} = 7x$

=> $\frac{ - 21}{4 \times 7} = x$

=> $x = \frac{ - 21}{28}$

=> $x = \frac{ - 3}{4}$

Hence, $x = \frac{ - 3}{4} \: is \: your \: answer$
