5) 30

6) -1/2

7) -1/3

8) 3

9) 5/7

10) 6

Explicación paso a paso:

1) 5x = 8x - 15

5x - 8x = -15

- 3x = -15

x = -15/-3

x = 5

2) 4x + 1 = 2

4x = 2 - 1

4x = 1

x = 1/4

3) x - 5 = 3x - 25

x - 3x = -25 + 5

-2x = -20

x = -20/-2

x = 10

4) 5x + 6 = 10x + 5

5x - 10x = 5 - 6

-5x = - 1

x = -1/-5

x = 1/5

5) 2x - 15 = 3x - 45

2x - 3x = -45 + 15

-x = -30

x = 30

6) 35 - 22x + 6 - 18x = 14 - 30x + 32

41 - 40x = 46 - 30x

-40x + 30x = 46 - 41

-10x = 5

x = - 5/10

x = - 1/2

7) 9x - 11 = -10 + 12x

9x - 12x = -10 + 11

-3x = 1

x = -1/3

8) 21 - 6x = 27 - 8x

-6x + 8x = 27 - 21

2x = 6

x = 6/2

x = 3

9) 11x + 5x - 1 = 65x - 36

16x - 1 = 65x - 36

16x - 65x = -36 + 1

- 49x = -35

x = -35/-49

x = 5/7

10) 8x - 4 + 3x = 7x + x + 14

11x - 4 = 8x + 14

11x - 8x = 14 + 4

3x = 18

x = 18/3

x = 6
