Answer 1

Respuesta:

Explicación paso a paso:

a) h + 17 = 15

h = 15 - 17

h = - 2

b) 9 + h = - 17

h = - 17 - 9

h = - 26

c) 4 + h = 0

h = - 4

d) h + 7 = 16

h = 16 - 7

h = 9

e) - 5 + h = -5

h = - 5 + 5

h = 0

f) 10 + h = 7

h = 7 - 10

h = - 3

g) 20 - (+h) = 9

20 - h = 9

- h = 9 - 20

- h = - 11

h = 11

h) h - (-6) = 7

h + 6 = 7

h = 7 - 6

h = 1

i) h + (-6) =0

h - 6 = 0

h = 6

j) (-5) + h = 4

-5 + h = 4

h = 4 +5

h = 9

k) h + 3 = -8

h = - 8 - 3

h = -11

l) h + (-7) = 12

h - 7 = 12

h = 12 + 7

h = 19

m) - 7 + h = -12

h = -12 + 7

h = - 5

n) - h + 5 = 13

- h = 13 - 5

- h = 8

h = -8

o) (-13) + (+h) = 9

-13 + h = 9

h = 9 + 13

h = 22

p) h - 16 = 30

h = 30 + 16

h = 46
