¡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
