Пошаговое объяснение:
1) 6х + 7 = 3х + 10
6х - 3х = 10 - 7
3х = 3
х = 3 : 3
х = 1
2) 5х + 7 = х – 1
5х - х = - 1 - 7
4х = - 8
х = - 8 : 4
х = - 2
3) 2x + 7 = 6x – 1
2х - 6х = - 1 - 7
- 4х = - 8
х = - 8 : (- 4)
х = 2
4) 2x - 7 = 4x + 3
2х - 4х = 3 + 7
- 2х = 10
х = 10 : (- 2)
х = - 5
5) 8х - 5 = 3х – 5
8х - 3х = - 5 + 5
5х = 0
х = 0 : 5
х = 0
6) 5x + 3 = 6x + 1
5х - 6х = 1 - 3
-х = - 2
