  1. Giải đáp:
    1/2x + 150%x = 2014
    1/2x + 3/2x = 2014
    (1/2 + 3/2)x = 2014
    2x = 2014
    x = 2014 : 2
    x = 1007
    Vậy x = 1007
     

  2. 1/2x + 150% x = 2014
    1/2 x + 3/2 x = 2014
    ( 1/2 + 3/2) x = 2014
    2 x                = 2014
    x                    = 2014 : 2
    x                    = 1007
