Question

7\18-3\4x=5\6x+4\9 решите уравнение

Answer 1

$\frac{7}{18}-\frac{3}{4}x=\frac{5}{6}x+\frac{4}{9}$
$-\frac{3}{4}x-\frac{5}{6}x=\frac{4}{9}-\frac{7}{18}$
$-\frac{9}{12}x-\frac{10}{12}x=\frac{8}{18}-\frac{7}{18}$
$-\frac{19}{12}x=\frac{1}{18}$
$x=\frac{1}{18}:(-\frac{19}{12})$
$x=\frac{1}{18}*(-\frac{12}{19})$
$x=-\frac{2}{57}$
