Question

решите уравнение 2х+5,2/-3=4,1/-1,5

Answer 1

$2x+ \frac{5.2}{-3}= \frac{4.1}{-1.5}$
$2x+ \frac{52}{10}:(-3)= \frac{41}{10} :(- \frac{3}{2} )$
$2x+ \frac{52}{10}*(- \frac{1}{3} )= \frac{41}{10} *(- \frac{2}{3} )$
$2x- \frac{52}{30}=- \frac{82}{30}$
$2x=- \frac{82}{30} +\frac{52}{30}$
$2x=-1$
$x=-0.5$
Ответ: -0,5
