1)

5/6x=-15

x = -15 * 6/5

x = -18

2)

-2 5/6x=17/18

-17/6x = 17/18

x = -17/18 * 6/17

x = -1/3

3)

4x=24+x

4x - x = 24

3x = 24

x = 24 : 3

x = 8

4)

8x-8=20-6x

8x + 6x = 20 + 8

14x = 28

x = 28 : 14

x = 2

5)

9-4x=3x-40

3x + 4x = 9 + 40

7x = 49

x = 49 : 7

x = 7

6)

0,6x-5,4=-0,8x+5,8

0,6x + 0,8x = 5,8 + 5,4

1,4x = 11,2

x = 11,2 : 1,4

x = 8

7)

4,7-1,1x=0,5x-3,3

0,5x + 1,1x = 4,7 + 3,3

1,6x = 8

x = 8 : 1,6

x = 5

8)

5/6x+16=4/9x+9

5/6x - 4/9x = 9 - 16

15/18x - 8/18x = -7

7/18x = -7

x = -7 * 18/7

x = -18
