Answer 1

Resposta:

a) 20 + 3 - 10

23 - 10

13

b) 45 + 4

49

c) 3x=30+3

3x = 33

x = 33/3 = 11

d) 2x + 2 = 40

2x = 40 - 2

2x = 38

x = 38/2 = 19

e) 5 + x = 10

x = 10 - 5

x = 5

f) 4x = 40 + 4

4x = 44

x = 44/4 = 11

g) 2x = 10 + 2

2x = 12

x = 12/2 = 6

h) 2x = 36 + 6

2x = 42

x = 42/2 = 21

i) 3x = 90 - 30

3x = 60

x = 60/3 = 20

j) 5x = 50 - 20

5x = 30

x = 30/5 = 6

k) 20x = 100 - 20

20x = 80

x = 80/20 = 4

espero ter ajudado :)
