Answer 1

Resposta:

a) x= 3

b) x=7

c) x = -1

d) x = -4

e) x=10

f) x= - 40

Answer 2

Olá!

a) x + 5 = 8

x = 8 - 5

x = 3

b) x - 4 = 3

x = 3 + 4

x = 7

c) x + 6 = 5

x = 5 - 6

x = -1

d) x - 3 = -7

x = -7 + 3

x = -4

e) x + 9 = -1

x = -1 - 9

x = -10

f) x - 39 = -79

x = -79 + 39

x = -40
