Question

3х+1/-2,7=-2,8/-3,6
Помогите пожалуйста решить

Answer 1

$\frac{3x + 1}{- 2,7} = \frac{- 2,8}{- 3,6}$
$\frac{3x + 1}{-\frac{27}{10}} = \frac{-\frac{14}{5}}{-\frac{18}{5}}$
$- \frac{(3x + 1)\times 10}{27} = \frac{- 14}{- 18}$
$- \frac{30x + 10}{27} = \frac{7}{9}$
$- 9 \times(30x + 10) = 189$
$30x + 10 = - 21$
$30x = - 21 - 10$
$30x = - 31$
$x = - \frac{31}{30}$
$x = - 1 \frac{1}{30}$
