Answer 1

Answer:

$\frac{ \frac{x}{4} - \frac{3}{5} }{ \frac{4}{3} - 7x} = - \frac{3}{20} \\ \frac{ \frac{5x - 12}{20} }{ \frac{4 - 21x}{3} } = - \frac{3 }{20} \\ \frac{4 - 21x}{3} = \frac{5x - 12}{20} \times ( - \frac{20}{3} ) \\ \frac{4 - 21x}{3} = \frac{ - (5x - 12)}{3} \\ \frac{3(4 - 21x)}{3} = - 5x + 12 \\ 4 - 21x = 12 - 5x \\ -21x + 5x = 12 - 4 \\ - 16x = 8 \\ x = - \frac{16}{8} \\ x = - 2$
