Odpowiedź:
a)
3x - 5 = 5x - 3
3x - 5x = - 3 + 5
- 2x = 2 /: (- 2)
x = - 1
b)
4x - 6 = 6x - 4
4x - 6x = - 4 + 6
- 2x = 2 / : (- 2)
x = - 1
c)
1/3x + 1/2(x + 1) = 1/6
1/3x + 1/2x + 1/2 = 1/6 /* 6
2x + 3x + 3 = 1
2x + 3x = 1 - 3
5x = - 2 / : 5
x = - 2/5
d)
1/2x + 1/3(x - 1) = 1/6
1/2x + 1/3x - 1/3 = 1/6 / * 6
3x + 2x - 2 = 1
3x + 2x = 1 + 2
5x = 3 /:5
x = 3/5
