Answer 1

tìm x biết 
a, x : 9 = 3856 + 28765

x : 9 = 32621

x = 32621 x 9

x = 293589

b, (x - 3245) x 4 = 24241 - 17213

(x - 3245) x 4 = 7028

(x - 3245) = 7028 : 4

(x - 3245) = 1757

x = 1757 + 3245

x = 5002.

 

Answer 2

a: =>x:9=32621

=>x=293589

b: =>4(x-3245)=7028

=>x-3245=1757

=>x=5002

Answer 3

A) X : 9 = 3856 + 28765           B) (X - 3245) x 4 = 24241 - 17213

     X : 9 = 32621                            (X - 3245) x 4 = 7028

     X      = 32621 x 9                       (X - 3245) x 4 = 7028 :4

     X      = 293589                           (X - 3245) x 4 =1757

                                                         X                   = 1757 + 3245

                                                         X                   = 5002
