Answer 11

x+78—54=56x7

x+78—54=392

x+78=446

x=446—78

x=368

Answer 12

x + 78 - 54 = 56 x 7

x + 78 - 54 = 392

x + 78        = 392 + 54

x + 78        = 446

      x          = 446 - 78

      x          = 368

Vậy x = 368

Answer 13

x + 78 - 54  = 56 x 7

x + 78 - 54  = 392

x +   24       = 392 

x                  = 392 - 24

x                  =  368

Vậy x = 368

Answer 14

x+78-54=56x7

x+78-54=392

x+78=392+54

x=78=446
