Answer 2

Ta có: n x 17 + 4 x n - n x 14 = 77

   => n x (17 + 4 - 14 ) = 77

   => n x 7                   = 77

   =>  n                        = 77 : 7

   =>  n                         = 11

Vậy n = 11

Answer 3

77 = n x ( 17 + 4 - 14  )

77 = n x 7 

n = 77 : 7 

n = 11

Answer 4

n x ( 17 + 4 - 14 ) =77

n x 7 = 77

n = 77 : 7

n = 11

Answer 5

n x 17 + 4x n - n x 14 = 77

n x ( 17 + 4 - 14 ) = 77

n x 7 = 77

n = 77 : 7 = 11

Answer 6

dễ ợt ~

Answer 7

=11 ok

Answer 8
