Question

a) (x-34).15=0          ;    b)18.(x-16)=18

Answer 1

a) (x - 34) . 15 = 0                               b) 18 . (x - 16) = 18

x - 34 = 0 : 15                                         x - 16 = 18 : 18

x - 34 = 0                                                x - 16 = 1

x = 0 + 34                                               x = 1 + 16

x = 34                                                    x = 17

Vậy x = 34                                             vậy x = 17

Answer 2

34;17

Answer 3

a, ( x - 34 ) . 15 = 0

( x - 34 ) = 0 :15

x - 34 = 0

x = 0 + 34

x = 34

Vậy x = 34

b, 18 . ( x - 16 ) = 18

( x - 16 ) = 18 : 18

x - 16 = 1

x = 1 + 16

x = 17

Vậy x = 17

Answer 4

a) ( x - 34 ) . 15 = 0

      x - 34          = 0 : 15

      x - 34          = 0

      x                 = 0 + 34

b) 18 . ( x - 16 ) = 18

            x - 16   = 18 : 18

            x - 16   = 1

            x          = 1 + 16

            x          = 17
