Question

$4x - \frac{3}{5} = 9$

​

Answer 1

$4x - \frac{3}{5} = 9 \\ \\ \frac{4x}{1} - \frac{3}{5} = 9 \\ \\ \frac{4x \times 5}{1 \times 5} - \frac{3}{5} = 9 \\ \\ \frac{20x}{5} - \frac{3}{5} = 9 \\ \\ \frac{20x - 3}{5} = 9 \\ \\ 20x - 3 = 9 \times 5 \\ \\ 20x - 3 = 45 \\ \\ 20x = 45 + 3 \\ \\ 20x = 48 \\ \\ x = \frac{48}{20} \: \: \: \\ \\ canceling \: \: by \: \: 2 \\ \\ x = \frac{24}{10} \\ \\ canceling \: \: by \: \: 2 \: \: again \\ \\ \boxed{x = \frac{12}{5} }$
