Answer 2

Answer:

$\bold \red{h} \bold\blue{i} \: \bold{m} \bold \purple{a} \bold \green{t} \bold \pink{e}$

$\huge\red{ \mid{ \underline{ \overline{ \tt a \pink{n} \blue{s} \purple{w} \gray{e} \orange{r}:-}} \mid}}$

$\frac{5}{4} - 7x = 9$

$- 7x = 9 - \frac{5}{4}$

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

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

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

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

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