Question

x-7/12x=4 1/6 решите задачу плиз

Answer 1

$frac{x-7}{12x} =4 frac{1}{6} \ frac{x-7}{12x} - frac{25}{6} =0 \ frac{x-7}{12x} - frac{25*2x}{12x} =0 \ frac{x-7-50x}{12x} =0 \ frac{-49x-7}{12x} =0 \ left { {{-49x-7=0} atop {12x neq 0}} right. \ left { {{-49x=7} atop {x neq 0}} right. \ left { {{x=- frac{7}{49} } atop {x neq 0}} right. \ left { {{x=- frac{1}{7} } atop {x neq 0}} right. \ \ x=- frac{1}{7}$

Answer 2

$x- frac{7}{12}x=4 frac{1}{6}$
$frac{5}{12}x= 4frac{1}{6}$
$x=4 frac{1}{6}: frac{5}{12} [tex] [tex]x= frac{25}{6}: frac{5}{12}$
$x= frac{25}{6}* frac{12}{5}$
$x=10$
$Otvet:10.$
