Answer 1

Resposta:

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 = 11

================================

D) x - 7 = -7

   x = - 7 + 7

   x = 0

================================

E) x + 9 = -1

   x = - 1 - 9

   x = -10

================================

F) x + 28 = 11

   x = 11 - 28

  x = -17

================================

G) x - 109 = 5

   x = 5 + 109

   x = 114

================================

H) x - 39 = -79

   x = -79 + 39

   x = -40

================================

I) 10 = x + 8

  10 - 8 = x

   2 = x

   x = 2

================================

J) 15 = x + 20

   15 - 20 = x

   -5 = x

    x = -5

================================

K) 4 = x - 10

   4 + 10 = x

   14 = x

  x = 14

================================

L) 7 = x + 8

   7 - 8 = x

   -1 = x

    x = -1

================================

M) 0 = x + 12

    0 - 12 = x

    -12 = x

    x = -12

================================

N) -3 = x + 10

   -3 - 10 = x

   -13 = x

    x = -13
