Answer 1

Explicación paso a paso:

$\frac{2}{5} x + - \frac{3}{8} = - \frac{7}{20} \\ \frac{2}{5} x = - \frac{7}{20} + \frac{3}{8} \\ \\ \frac{2}{5} x = \frac{ - 14 + 15}{40} \\ \frac{2}{5} x = \frac{1}{40} \\ x = \frac{1}{40} \div \frac{2}{5} = \\ \frac{5}{80} \: simplificas \: y \: queda \\ \frac{1}{16}$
