Question

Tìm x:

(x-105):21=15

 

Answer 1

( x - 105) : 21 = 15

x - 105 = 315

x = 420 

Answer 2

( x - 105 ) : 21 = 15

( x - 105 )        = 15 x 21 

( x - 105 )        =   315

  x                  = 315 + 105

  x                  =    420 

Answer 3

\(\left(x-105\right):21=15\)

\(x-105=15\times21\)

\(x-105=315\)

         \(x=315+105\)

         \(x=420\)

Answer 4

( x - 105 ) : 21 = 25 

x - 105 = 21 . 25 

x - 105 = 525

x = 525 + 105 

x = 630

mik đầu tiên đó

Answer 5

( x - 105 ) : 21 = 15

( x - 105 ) = 15 x 21

( x - 105 ) = 315

x             = 315 + 105

x             = 402

Answer 6

[x-105]:21=15

x-105=15x21

x-105=315

x=315+105

x=420

Answer 7

Nhầk

( x - 105 ) : 21 = 15

( x - 105 ) = 15 x 21

( x - 105 ) = 315

x             = 315 + 105

x             = 320

Answer 8

( x - 105 ) : 21 = 15
