alguém ajuda pfv​

Answer 1

Resposta:

a) x + 8 = 20

x = 20 - 8

x = 12

_______________

d) 3y - 8 = 13

3y = 13 + 8

3y = 21

y = 21/3

y = 7

________________

b) y - 15 = 13

y = 13 + 15

y = 28

________________

e) 4x - 4 = 32

4x = 32 + 4

4x = 36

x = 36/4

x = 9

c) x - 8 = 3

x = 3 + 8

x = 11
