Answer 1

$\sf \color{lime} \: \frac{5x - 9}{3} \: = \: \frac{7}{2} \\ \\ \bold{Cross\: Multiplying} \\ \\ \sf \color{lime} \:(5x - 9) \: \times \: (2) \: = \: 7 \: \times \: 3 \\ \\ \sf \color{lime} \:10x \: - \: 18 \: = \: 21 \\ \\ \sf \color{lime} \:10x \: = \: 21 \: + \: 18 \\ \\ \sf \color{lime} \:10x \: = \: 39 \\ \\ \sf \color{lime} \:x \: = \: \frac{39}{10} \\ \\ \sf \color{red} \: \boxed{ \sf \: x \: = \: 3.9}$
