Odpowiedź:

a) 4x - 3x = 3 + 5

x = 8

b) 5x + 3x = - 2 + 7

8x = 5 |:8

x = ⁸/5

c) 3x - 3 = 0

3x = 3 + 0

3x = 3 |:3

x = 1

d) -6x - 6 = 24

-6x = 6 + 24

-6x = 30 |:(-6)

x = -5

e) -7x + 14 = 3x - 1

-7x - 3x = -14 - 1

-10x = -15 |:(-10)

x = 10/15 = ⅔

f) 4x - 4 = 6 + 6x

4x - 6x = 4 + 6

-2x = 10 |:(-2)

x = -5
