Question

3.8/0.1x+3=10/11
ПО щагово мені тре зробити

Answer 1

$frac{3,8}{0,1x} +3 = frac{10}{11}$
$frac{3,8}{0,1x} = frac{10}{11} -3$
$frac{3,8}{0,1x} = frac{10}{11} - frac{33}{11}$
$frac{3,8}{0,1x} = - frac{23}{11}$
$0,1x = frac{3,8}{- frac{23}{11}}$
$0,1x = (3frac{8}{10}) /(- frac{23}{11})$
$-frac{1}{10} x = frac{38}{10}*frac{11}{23}$
$frac{1}{10} x = -frac{418}{230}$
$x = (-frac{418}{230})/( frac{1}{10})$
$x = -frac{418}{230}* frac{10}{1}$
$x = -frac{4180}{230}$
$x = -18frac{4}{23}$
