Answer 4

x + 87 = 97

x = 97 - 87

x = 10

x - 28 = 18

x = 18 + 28

x = 46

28 + x = 56

x = 56 - 28

x = 28

85 - x = 56

x = 85 - 56

x = 29

Answer 5

x + 87 = 97                         x - 28 = 18                        28 + x = 56                  85 - x = 56

       x = 97 - 87                           x = 18 + 28                      x = 56 - 28                  x = 85 - 56 

       x = 10                                 x = 46                              x = 28                         x =29

Answer 6

x + 87 = 97

x = 97 - 87 

x = 10

x - 28 = 18

x = 18 + 28

x = 46

28 + x = 56

x = 56 - 28

x = 28

85 - x = 56

x = 85 - 56

= 29

Answer 7

a/x=97-87 x=10 b/x=18+28 x=46 c/ x=56-28 x=28 d/x=85-56 x=29

Answer 8

x + 87 = 97

x = 97 - 87

x = 10

x - 28 = 18

x = 18 + 28

x = 46

28 + x = 56

x = 56 - 28

x = 28

85 - x = 56

x = 85 - 56

x = 29
