Step-by-step explanation:

Answer 2

Answer:

35 + (-35) = 0

-3525 + 7050 = 3525

(-25) + 52 = 27

83 - 71 = 12

15 + 15 = 30

Step-by-step explanation:

a)

x - 35 = 0

x = 35

35 + (-35) = 0

15 + 15 = 30

b)

-3525 + x = 3525

x = 3525 + 3525

x = 7050

-3525 + 7050 = 3525

d)

x + 52 = 27

x = 27 - 52

x = -25

(-25) + 52 = 27

e)

83 + x = 12

x = 12 - 83

x = -71

83 - 71 = 12

g)

x + (-15) + 7 = 15

x - 8 = 15

x = 15 + 8

x = 23

23 + (-15) + 7 = 15

h)

15 + x = 30

x = 30 - 15

x = 15

15 + 15 = 30
