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: $-1 \frac{1}{3}$
