Question

а) 0,8х + 14 = 2 – 1,6х;
б) 2 – 3(х + 2) = 5 – 2х;

Answer 1

$a)0.8*x + 14 = 2 - 1.6*x |*5$
$4x+70 = 10 - 8x$
$12*x = -60$
$x = -5$

$b)2-3*(x+2) = 5 -2*x$
$2-3*x-6 = 5 -2*x$
$2-x-6 = 5$
$x =2-6-5$
$x = -9$

Answer 2

окей

Answer 3

извините еще раз

Answer 4

а)0,8х+14=2-1,6х
0,8х+14-2+1,6х=0
2,4х+12=0
2,4х=-12
х=-5
ответ:-5
б)2-3(х+2)=5-2х
2-3х-6=5-2х
-3х-4=5-2х
-3х+2х=5+4
-х=9
х=-9
ответ: -9
