Решите уравнение:

4x+5 (3-2x) = 5-11x;

19-2 (3x+8) = 2x-37;

8x+3 (7-2x) = 4x+3;

23-4 (3x+8) = 1-17x;

1) 4x+5 (3-2x) = 5-11x;

4x+15-10x=5-11x

4x-10x+11x=5-15

5x=-10

x=-2

2) 19-2 (3x+8) = 2x-37

19-6x-16=2x-37

-6x-2x=-37+16-19

-8x=-40

x=5

3) 8x+3 (7-2x) = 4x+3;

8x+21-6x=4x+3

8x-6x-4x=3-21

-2x=-18

x=9

4) 23-4 (3x+8) = 1-17x;

23-12x-32=1-17x

-12x+17x=1-23+32

5x=10

x=2

4x=15-10x=5-11x

4x+11x-10x=5-15

5x=-10

x = - 2

19-6x-16=2x-37

3-6x=2x-37

3+37=2x+6x

40=8x

x = 5

8x+21-6x=4x+3

8x-6X-4x=3-21

-2x=-18

x=9

23-12x-24=1-17x

23-32-1=12x-17x

-10=-5x

x=2
