Question

решите уравнение

10 - 2 ( 3 x + 5 = 4 ( x - 2 )

Answer 1

10-2(3x+5)=4(x-2)
10-6х+10=4х-8
4х-6х=-8-10-10
2х=-28
х=-14

Answer 2

ну

Answer 3

10 - 2(3x+5)=4(x-2);

10 - 6x -10 = 4x-8;

10-10+8 = 6x + 4x;

8= 10x;

x= 0,8.



Ответ: 0,8.

Answer 4

-6x-10-4x+8=-10
-6x-4x+8=0
-10x+8=0
-10x=-8 |:(-10)
x=$frac{8}{10}$=$frac{4}{5}$
