Question

1) Resolva as equações:
A) 2x-7=9
B) 4x+1=37
C) 5x+1=16
D) 2x=18
E) 5x=-15
F) 4x=24

Answer 1

A) 2x - 7 = 9

2x = 9+7

2x = 16

x = 16/2

x = 8

B) 4x + 1 = 37

4x = 37-1

4x = 36

x = 36/4

x = 9

C) 5x + 1 = 16

5x = 16-1

5x = 15

x = 15/5

x = 3

D) 2x = 18

x = 18/2

x = 9

E) 5x = -15

x = -15/5

x = -3

F) 4x = 24

x = 24/4

x = 6

Answer 2

Resposta:

A)X= 8

B)X= 9

C)X= 3

D)X= 9

E)X= -3

F)X= 6
