1)2-3(2х+2) = 5-4х

2-(6х-6) = 5-4х

2-6х+6 = 5-4х

-6х+4х = 5-2+6

-2х = 9

х = -9/2

2)8-5(2х-3) = 13-6х

8-(10х-15) = 13-6х

8-10х+15 = 13-6х

-10х+6х = 13-8-15

-4х = -10

х = 10/4 = 5/2

3)1-2(5-2х) = -х-3

1-(10-4х) = -х-3

1-10+4х = -х-3

4х+х = -3-1+10

5х = 6

х = 6/5

4)1-7(4+2х) = -9-4х

1-(28+14х) = -9-4х

1-28-14х = -9-4х

-14х+4х = -9-1+28

-10х = 18

х = -18/10 = -9/5
