a) 1/3x - 2 = x + 2 | * 3

3x - 6 = 3x + 6

3x - 3x = 6 + 6

0x = 12

b) 1 - 6/7x = 4/7 | * 7

7 - 6x = 4

-6x = 4 -7

-6x = 3 | : (-6)

x = 3/6 = 1/2

c) 6(1/4x - 2) = 18

3/2x - 12 = 18 |*2

3x - 24 = 36

3x = 36 + 24

3x = 60 | : 3

x = 20

d) x/6 - 1/6 = 1 |*6

x - 1 = 6

x = 6 + 1

x = 7

e) -2(2x - 1) = x/3

-4x + 2 = x/3 | * 3

- 12x + 6 = x

-12x - x = - 6

-13x = - 6 |: (-13)

x = 6/13

f) 2/5 (3 - x) = -2 |* 5

2(15 - 5x) = - 10

30 - 10x = - 10

- 10x = -10 - 30

- 10x = - 40 |: (-10)

x = 4
