Question

1. 5/6-( y+2/3)=1. 1/2

Answer 1

$frac{5}{6} -(y+ frac{2}{3} )=1 frac{1}{2}$
$frac{5}{6} -y- frac{2}{3} = frac{3}{2}$
$frac{5}{6} -y- frac{4}{6} = frac{9}{6}$
$frac{1}{6} -y= frac{9}{6}$
$y= frac{1}{6} - frac{9}{6}$
$y= -frac{8}{6}$
$y=- frac{4}{3}$
$y=-1 frac{1}{3}$
Ответ: $y= -1 frac{1}{3}$.

Answer 2

Решение:
$frac{5}{6} - (y + frac{2}{3} ) = 1 frac{1}{2}$
$y + frac{2}{3} = frac{5}{6} - 1 frac{1}{2}$
$y + frac{2}{3} = - frac{9}{6} + frac{5}{6}$
$y + frac{2}{3} = - frac{4}{6}$
$y + frac{2}{3} = - frac{2}{3}$
$y = - frac{2}{3} - frac{2}{3}$
$y = -1 frac{1}{3}$

Ответ: $-1 frac{1}{3}$
