Answer 2

a , x = 17

Answer 3

a, x=17 

b, x=39

c, x=12

d, x=90

Answer 4

Tìm x :

a. 34 + x = 51

            x = 51 - 34

            x = 17 

b. 58 - x = 19

           x = 58 - 19

           x = 39

c. 32 - x = 19

           x = 32 - 19 

           x = 13

d. x - 9 = 81

    x      = 81 + 9

    x      = 89

Answer 5

a) \(34+x=51\)

x = 51 - 34

x = 17

b) 58 - x = 19

x = 58 - 19

x = 31

c) 32 - x = 19

x = 32 - 19

x = 13

d) x - 9 = 81

x = 81 + 9

 x = 90

Answer 6

a. 34 + x = 51                      b. 58 - x = 19                  c. 32 - x = 19                         d. x - 9 = 81

            x  = 51 - 34                         x = 58 - 19                      x = 32 - 19                            x = 81 + 9

             x = 17                                 x = 39                             x = 13                                   x = 90

Answer 7

a) x = 51-34= 17

b) x= 58-19 = 39

c) x= 32-19= 13

d) 81+9= 90

Answer 8

a

x=51-34=17

b

x=58-19=39

c

x=32-19=13

d

x=81+9=100

Answer 9

a ) 34 + x = 51

x = 51 - 34

x = 17

b ) 58 - x = 19

x = 58 - 19

x = 39

c ) 32 - x = 19

x = 32 - 19 

x = 13

d ) x - 9 = 81

x = 81 + 9

x = 90
