Question

718-34x=56x+49 решите уравнение

Answer 1

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