Question

СРОЧНО!!!!!! решите уравнение)) 3х=15.....4х-2=14.....4х-2=2х+6.....2х-2=6+4х.....3х+х+2=18.....3х-12=х.....2х+6=4х-2.....-4х-4=2х+8.....

Answer 1

1) 3х = 15
х=15:3
х = 5
2) 4х - 2= 14
4х = 14 + 2
4х = 16
х = 16:4
х = 4
3) 4х - 2=2х+6
4х-2х = 6 +2
2х = 8
х=8:2 
х=4
4) 2х-2 = 6+4х
4х - 2х = -6-2
2х = -8
х=-8:2
х=-4
5) 3х + х+2=18
4х = 18 -2
4х = 16
х=16:4
х=4
6)3х-12=х
3х-х=12
2х=12
х=12:2
х=6
7) 2х+6=4х-2 решение такое же как и 3)
8) -4х-4=2х+8
2х+4х=-4-8
6х=-12
х=-12:6
х=-2
