Question

( x + 34 x 9 ) + 47 x 9 = 2184

Answer 1

( x + 34 x 9 ) + 47 x 9 = 2184

( x + 34 x 9 ) + 423 = 2184

( x + 34 x 9 ) = 2184 - 423 

x + 34 x 9 = 1761

x + 306 = 1761

x = 1761 - 306

x = 1455

 Vậy x = 1455

Answer 2

(x+34x9)+47=2184:9

x+306=728/3-47

x=587/3-306

x=-331/3

Answer 3

( x + 34 x 9 ) + 47 x 9 = 2184

( x + 34 x 9 ) + 423    = 2184

  x + 306                   = 2184 - 423

  x + 306                   = 1761

  x                             = 1761 - 306

  x                             = 1455

Answer 4

( x + 306 ) + 423 = 2184

x = 2184 - 423

x = 1761 - 306

x = 1455
