Resposta:

a) -2

b) 7

c) 24

d) -3

e) 1

f) -4

g) 0

h) 3

Explicação passo-a-passo:

LETRA A

2x = -4

x= -4/2

x = -2

_________________________________________

LETRA B

3x = 21

x= 21/3

x = 7

_________________________________________

LETRA C

2x = 48

x = 48/2

x = 24

_________________________________________

LETRA D

-3x = 9

x = 9/-3

x = -3

_________________________________________

LETRA E

2x + 4 = 6

2x = 6 - 4

2x = 2

x = 2/2

x = 1

________________________________________

LETRA F

4x = -16

x = -16/4

x = -4

_________________________________________

LETRA G

-2x = 0

x = 0/-2

x = 0

_________________________________________

LETRA H

3x + 1 = 10

3x = 10-1

3x = 9

x = 9/3

x = 3
