Odpowiedź:

3 x + 2  = 5

3 x = 5 - 2

3 x = 3 / :3

x = 1

======

7 x - 6 = - 6 x + 7

7 x + 6 x = 7 + 6

13 x = 13 / : 13

x = 1

=====

- 7 *( 2 x + 1  ) = 4  / : ( -7 )

2 x + 1 = - [tex]\frac{4}{7}[/tex]

2 x = - [tex]\frac{4}{7} - \frac{7}{7}[/tex]

2 x  = - [tex]\frac{11}{7} / : 2[/tex]

x = - [tex]\frac{11}{14}[/tex]

===========

[tex]\frac{1}{3} x + 2 = x / * 3[/tex]

x + 6 = 3 x

6 = 3 x - x

2 x = 6  / : 2

x = 3

=======

8 = 6*( x - 1) - 4 x

8 = 6 x - 6 - 4 x

8 =  2 x - 6

8 + 6 = 2 x

2 x = 14  / : 2

x = 7

======

16 x - 2 = 20 x + 4

- 2 - 4 = 20 x - 16 x

- 6 = 4 x   / : 4

x =  - 1.5

========
