Question

СРОоооооочно, 5/6(1/3х- 1/5)=7х- 4(х- 5/6)

Answer 1

$frac{5}{6} * frac{x}{3} - frac{5}{6} * frac{1}{5} =7x-4x+4* frac{5}{6}; \ frac{5x}{18} - frac{1}{6} =3x+ frac{20}{6} \ - frac{21}{6} =3x-frac{5x}{18} \ - frac{21}{6} =frac{54x-5x}{18} \ - frac{21}{6} =frac{49x}{18} \ - 21 =frac{49x}{3} \ - 3 =frac{7x}{3} \ x=- frac{9}{7}$
