Решите уравнение:

1) 4x+5 (3-2x) = 5-11x 3) 8x+3 (7-2x) = 4x+3

2) 19-2 (3x+8) = 2x-37 4) 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=-37-19+16

-8x=-40

x=5

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

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

2x-4x=3-21

-2x=-18

x=9

4) 23-4 (3x+8) = 1-11x

23-12x+24=1-11x

-12x+11x=1-23-24

-x=-48

x=48
