РЕШИТЕ УРАВНЕНИЕ 1)6x-12=4X-82)2/3x=183) (2x-5)-(3x-7)=44) 5(x-1,2)-3x-2ДАМ 150 БАЛЛОВ

Answer 1

6х - 12 = 4х - 8
6х - 4х = 12 - 8
2х = 4
х = 2
2\3х = 18
2х = 54
х = 17
(2х - 5) - (3х - 7) = 4
2х - 5 - 3х + 7 = 4
-х = 4 + 5 - 7
-х = 2
х = -2
5(х - 1.2) - 3х - 2 =
5х - 6 - 3х - 2 =
2х - 8=
2(х - 4)
