Пошаговое объяснение:
1)
5 + 4х = 6 + 3х
4x - 3x = 6 - 5
x = 1
2)
5х – 3 = 3х + 1
5x - 3x = 1 + 3
2x = 4
x = 4 : 2
x = 2
3)
-8 + 2х = х - 5
2x - x = 8 - 5
x = 3
4)
9 – 3х =1 + х
x + 3x = 9 - 1
4x = 8
x = 8 : 4
x = 2
5)
6х – 7 = 8 + 3х
6x - 3x = 8 + 7
3x = 15
x = 15 : 3
x = 5
6)
4х – 2 = 10 + 2х
4x - 2x = 10 + 2
2x = 12
x = 12 : 2
x = 6
7)
3 – 4х = 17 – 6х
6x - 4x = 17 - 3
2x = 14
x = 14 : 2
x = 7
8)
9х – 1 = 8 х + 7
9x - 8x = 7 + 1
x = 8
9)
4х – 6 = 2х + 12
4x - 2x = 12 + 6
2x = 18
x = 18 : 2
x = 9
10)
3х + 3 = 2х + 13
3x - 2x = 13 - 3
x = 10
