Răspuns:

a) x + 83 = 93

x = 93 - 83

x = 10

b) x - 36 = 64

x = 64 + 36

x = 100

c) 114 - x = 33

x = 114 - 33

x = 81

d) 5( x + 17 ) = 125

5x + 85 = 125

5x = 125 - 85

5x = 40

x = 40 : 5

x = 8

e) 13 x = 169

x = 169 : 13

x = 13

f) 148 - ( 2x + 5 ) = 3

148 - 3 = 2x + 5

145 = 2x + 5

145 - 5 = 2x

140 = 2x

x = 140 : 2

x = 70

g) x : 2 = 1000

x = 1000 × 2

x = 2000

h) 2013 : x = 1

x = 2013 : 1

x = 2013
