​

Answer 1

Ответ:

$(3\frac{1}{8} +1\frac{3}{4})x =2\frac{1}{6} \\\\(\frac{25}{8}+\frac{7}{4})x= \frac{13}{6} \\\\(\frac{25}{8}+\frac{14}{8})x=\frac{13}{6}\\\\\frac{39}{8}x=\frac{13}{6} \\\\x=\frac{13}{6}:\frac{39}{8} \\\\x=\frac{13}{6} *\frac{8}{39}\\\\x=\frac{1}{3}*\frac{4}{3}\\\\x=\frac{4}{9}$
