Решите уравнение:

1) 4 х+5 (3-2 х) = 5-11 х;

2) 19-2 (3 х+8) = 2 х-37;

3) 8 х+3 (7-2 х) = 4 х+3;

4) 23 - (3 х+8) = 1-17 х

помогите прошу

1) 4 х+5 (3-2 х) = 5-11 х;

4 х+15-10 х=5-11 х

4 х-10 х+11 х=5-15

5 х=-10

х=-10:5

х=-2

2) 19-2 (3 х+8) = 2 х-37;

19-6 х-16=2 х-37

-6 х-2 х=-37+16-19

-8 х=-40

х=-40: (-8)

х=5

3) 8 х+3 (7-2 х) = 4 х+3;

8 х+21-6 х=4 х+3

8 х-6 х-4 х=3-21

-2 х=-18

х=-18: (-2)

х=9

4) 23 - (3 х+8) = 1-17 х

23-3 х-8=1-17 х

-3 х+17 х=1+8-23

14 х=-14

х=-14:14

х=-1
