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
