Question

5/8*(х-2)-2/3*(х+2)= -1 есоеэсто /-это дробная палочка помогите прошу!!!!-

Answer 1

$frac{5}{8}(x-2)-frac{2}{3}(x+2)=-1$
$frac{5}{8}x-2*frac{5}{8}-frac{2}{3}x-frac{2}{3}*2=-1$
$frac{5}{8}x-frac{2}{3}x-2*frac{5}{8}-frac{2}{3}*2=-1$
$frac{5}{8}x-frac{2}{3}x-frac{5}{4}-frac{4}{3}=-1$
$frac{5}{8}x-frac{2}{3}x-frac{15}{12}-frac{16}{12}=-1$
$frac{5}{8}x-frac{2}{3}x-frac{31}{12}=-frac{12}{12}$
$frac{15}{24}x-frac{16}{24}x=-frac{12}{12}+frac{31}{12}$
$-frac{1}{24}x=frac{19}{12}$
$x=frac{19}{12}:(-frac{1}{24})$
$x=frac{19}{12}*(-24)$
$x=19*(-2)$
$x=-38$
