Question

Решите уравнение
0,2(5х-4)=3,2-(6-2х)

Answer 1

Ответ:

0,2(5х-4)=3,2-(6-2х)

1х-0,8=3,2-6+2х

1х-2х=3,2-6+0,8

-1х=-2

х=2

Answer 2

$0.2(5x - 4) = 3.2 - (6 - 2x)$

$x - 0.8 = 3.2 - (6 - 2x)$

$x - 0.8 = 3.2 - 6 + 2x$

$x - 0.8 = - 2.8 + 2x$

$x - 0.8 - 2x = - 2.8$

$x - 2x = - 2.8 + 0.8$

$- x = - 2.8 + 0.8$

$x = 2$
