Answer 2

Ответ:

x=2

Пошаговое объяснение:

$(\frac{3}{5}x-\frac{2}{3})*30=16\\\\ \frac{3}{5}x-\frac{2}{3}=\frac{16}{30}\\\\ \frac{3}{5}x=\frac{8}{15}+\frac{2}{3}\\\\ \frac{3}{5}x=\frac{8}{15}+\frac{10}{15}\\\\ \frac{3}{5}x=\frac{18}{15}\\\\ x=\frac{18}{15}:\frac{3}{5}\\\\ x=\frac{18}{15}*\frac{5}{3}\\\\ x=\frac{6}{3}\\\\ x=2$
