Odpowiedź:

a) 5x = 130 |:5

x = 26

b) 4x + 12 = 36

4x = 36 - 12

4x = 24 |:4

x = 6

c) 7x - 22 = 27

7x = 27 + 22

7x = 49 |:7

x = 7

d) 3x - 8 - x = 9 - 2x - 3

3x - x + 2x = 9 - 3 + 8

4x = 14 |:4

x = 3,5

Odpowiedź:

x = 130 : 5

x = 26

x = 36 - 12

x = 24/: 4

x = 6

x = 27 + 22

x = 49/: 7

x = 7

2x - 8 = 6 - 2x = 2x + 2x =6 + 8 = 4x =6 + 8 = 4x = 14

14 : 4

x = 7/2 = 3 1/2 = 3,5
