Помогите решить уравнения

1) 6x+18=0

2) 2x+3=3x-2

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

4) 3/4 (4+8) = 9 (7x-1)

5) (7-10x) - (8-8x) + (10x+6) = - 8

6x = - 18

x = - 18/6

x = - 3

2x - 3x = - 3 - 2

- x = - 5

x = 5

15 - 3x = 11 + 2x

- 3x - 2x = - 15 + 11

- 5x = - 4

5x = 4

x = 4/5

x = 0,8

3 + 6 = 63x - 9

- 63x = - 9 - 9

- 63x = - 18

63x = 18

x = 18/63

x = 6/21

x = 2/7

7 - 10x - 8 + 8x + 10x + 6 = - 8

8x = - 8 - 5

8x = - 13

x = - 13/8

x = - 1,625
