Answer 1

6х-4х=7-1

2х=6

Х=3

х=-5+3

Х=-2

4х-7х+2=17

-3х=17-2

-3х=15

Х=-5

2х=4,4+0,6

2х=5

Х=2,5

-3х=-4-5

-3х=-9

Х=3

Answer 2

6х+1=4х+7;
6х-4х=7-1
2х=6
х=6:2
х=3

2х-3=х-5;
2х-х=-5+3
х=-2

 4Х-(7Х-2)=17;
4х-7х+2=17
-3х=17-2
-3х=15
х=-15:3
х=-5

3Х-0,6=Х+4,4;
3х-х=4,4+0,6
2х=5
х=5:2
х=2,5

5-Х=2Х-4;
-х-2х=-4-5
