Question

2,3-1.6x=7/12 x + 5,9

Answer 1

2.3-1.6x=7:12x + 5.9

2.3-1.6x=$frac{7}{12} x$+5.9
-1.6x - $frac{7}{12}$x=5.9-2.3
-1.6x- $frac{7}{12}$x=3.6
-$frac{16}{10}$x -$frac{7}{12}$x=3.6
-$frac{8}{5}$x-$frac{7}{12}$x=3.6
$frac{12*-8-5*7}{60} x$=3.6
$frac{-96-5*7}{60} }$x=3.6
$frac{-96-35}{60}$x=3.6
$frac{-131}{60}$x=3.6
-$frac{131}{60}$x=3.6
x=3.6 : ($- frac{131}{60}$)
x=$frac{36}{10}$ : ($-frac{131}{60}$)
x=$frac{18}{5}$ : ($- frac{131}{60}$)
x=$frac{18}{5}$ * ($-frac{60}{131}$)
x=18*($- frac{12}{131}$)
x=$- frac{18*12}{131}$
Ответ: x= $- frac{216}{131}$

Надеюсь правильно.
