Question

помогите с уравнением

Answer 1

$frac{3}{5}*(frac{7}{9}x-frac{1}{3})=x-2frac{1}{3}$
$frac{7}{15}x-frac{1}{5}=frac{15}{15}x-frac{7}{3}$
$frac{7}{15}x-frac{15}{15}x=frac{3}{15}-frac{35}{15}$
$-frac{8}{15}x=-frac{32}{15}$
$x=-frac{32}{15}:(-frac{8}{15})$
$x=-frac{32}{15}*(-frac{15}{8})$
$x=4$
