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

a,(x-34).15=0

   (x-34)=0

   x=34

Vậy x=34

b, 18.(x-16)=18

     x-16=1

    x=17

Vậy x=17
