Resposta:

a ) x + 2 = 6 '

x= 6-2

x = 4

B ) x +8 = 5

x = 5 - 8

x = - 3

C ) x - 3 = 6

x = 6 + 3

x = 9

D ) x - 3 = - 4

x = - 4+3

x = - 1

E ) x -7 = - 1

x = - 1 + 7

x = 6

F ) x + 2 = -9

x = - 9 - 2

x = - 11

G ) x + 7= 7

x = 7 _ 7

x = 0

H ) x - 6 = 6

x = 6 + 6

x = 12

I ) x + 8 = 0

x = 0 _ 8

x = - 8

J ) x - 11 = 20

x = 20 + 11

x = 31
