¡Hola!

A) 2x = 8
x = 8/2
x = 4

B) - 3x = 21
x = 21/ -3
x= -7

C) 4x = 20
x = 20/4
x = 5

D) 5x = - 80
x = - 80 / 5
x = -16

E) 6x = 120
x = 120 / 6
x = 20

F) 7x = 1
x = 1/7

G) 2x + 9 = 19
2x = 19 - 9
2x = 10
x = 10 / 2
x = 5

H) - 3x + 7 = 22
7 - 22 = 3x
-15 = 3x
-15 / 3 = x
- 5 = x

I) 4x - 5 = 37
4x = 42
x = 42 / 4
x = 21 / 2

J) 5x + 13 = - 23
5x = - 23 - 13
5x = - 36
x = - 36 / 5

K) 6x - 24 = 72
6x = 72 + 24
6x = 96
x = 96 / 6
x = 16

L) 2x - 1 = - 5
2x = - 5 + 1
2x = - 4
x = - 4 / 2
x= - 2

M) 4x - 2 = 6
4x = 6 + 2
4x = 8
x = 8 / 4
x = 2

N) - 3x - 4 = 23
-4 - 23 = 3x
- 27 = 3x
-27 / 3 = x
- 9 = x

O) 5x - 10 = 30
5x = 30 + 10
5x = 40
x = 40 / 5
x = 8

P) - 6x - 45 = 15
- 45 - 15 = 6x
- 60 = 6x
- 60 / 6 = x
- 10 = x

Q) 2x - 8 + 6 = 8
2x - 2 = 8
2x = 10
x = 10 / 2
x = 5

R) 3x + 4 -  9 = 10
3x - 5 = 10
3x = 15
x = 15 / 3
x = 5

S) - 4x - 3 + 7 = 29 - 5
- 4x + 4 = 24
4 - 24 = 4x
- 20 = 4x
- 20 / 4 = x
- 5 = x

T) 5x + 3 - 5 = 70 - 27
5x - 2 = 43
5x = 43 + 2
5x = 45
x = 45 / 5
x = 9

Espero que te sirva de ayuda ;D
