Resolva as equações:

a) 7x=14
b) 3x=21
c) 4x= -12
d) 3x=9
e) 6x= -6
f) 2x=8

Answer 1

Resposta:

x=14/7=2

x=21/3=7

x=-12/4= -3

x=9/3=3

x= -6/6= -1

x=8/2=4

Answer 2

Resposta:

A) 7x = 14

x = 14 ÷ 7

x = 2

B) 3x = 21

x = 21 ÷ 3

x = 7

C) 4x = -12

x = -12 ÷ 4

x = - 3

D) 3x = 9

x = 9 ÷ 3

x = 3

E) 6x = -6

x = 6 ÷ -6

x = -1

F) 2x = 8

x = 8 ÷ 2

x = 4
