Answer 1

x - 60 = 85

x = 85 + 60

x = 145

145 - 60 = 85

x - 41 = 98

x = 98 + 41

x = 139

139 - 41 = 98

x - 96 = 84

x = 84 + 96

x = 180

180 - 96 = 84

x - 36 = 6

x = 6 + 36

x = 42

42 - 36 = 6

157 - x = 140

x = 157-140

x = 17

157 - 17 = 140

96 - x = 16

x = 96-16

x = 80

96 - 80 = 16

75 - x = 19

x = 75-19

x = 56

75-56 = 19

121 - x = 14

x = 121-14

x = 107

121 - 107 = 14
