C) 4x = -12
D) 7x = -21
E) 13x = 13
F) 9x = -9

Answer 1

Resposta:

A) 3x = 15

x= 15/3

x= 5

B) 2x = 14

x= 14/2

x=7

C) 4x = -12

x= -12/4

x= -3

D) 7x = -21

x= -21/7

x= -3

E) 13x = 13

x= 13/13

x= 1

F) 9x = -9

x= -9/9

x= -1

Answer 2

Resposta:

A)

3x = 15

x = 15/3

x = 5

B)

2x = 14

x = 14/2

x = 7

C)

4x = - 12

x = - 12/4

x = - 3

D)

7x = - 21

x = - 21/7

x = - 3

E)

13x = 13

x = 13/13

x = 1
