$\huge{\underline{\mathfrak{\textcolor{blue}{Answer :}}}}$

$\huge\boxed{\fcolorbox{red}{#ffdfff}{b = 3 \: \: and \: \: x = -5}}$

$\LARGE{\underline{\mathrm{\textcolor{red}{Step-by-step \: \: explanation :}}}}$

$\boxed{a}$

$\implies 27 = 9b$

$\implies 9b = 27$

$\implies b = \frac{27}{9}$

$\implies b = \frac{9 \times 3}{9}$

$\implies b = \frac{1 \times 3}{1}$

$\implies b = 3$

$\boxed{b}$

$\implies 2x + 7 = - 3$

$\implies 2x = - 7 - 3$

$\implies 2x = - (7 + 3)$

$\implies 2x = - 10$

$\implies x = \frac{ - 10}{2}$

$\implies x = - \frac{2 \times 5}{2}$

$\implies x = - \frac{1 \times 5}{1}$

$\implies x = - 5$
