  1. 1) x – 1/2 = 3/6
       x  = 3/6 + 1/2 
       x = 3/6 + 3/6
       x = 6/6 = 1.
    Vậy x =1 
    2) 9/5 + x = 3/8
                 x   = 3/8 – 9/5
                 x =  -57/40
    Vậy x = -57/40
    3) 500 – x = 4236
                  x   = 500 – 4236
                  x   = -3736
    Vậy x = -3736
    4) 1235 + x = 6359
                    x = 6359 – 1235
                    x   = 5124
    Vậy x = 5124
    5) 15/2 . x = 5/9
                  x = 5/9 : 15/2
                  x = 2/27
    Vậy x = 2/27

  2. a) x – 1/2 = 3/6
        x = 3/6 + 1/2
        x = 3/6 + 3/6
        x = 6/6 = 1
    b) 9/5 + x = 3/8
        x = 3/8 – 9/5
        x = 15/40 – 72/40
        x = -57/40
    c) 500 – x = 4236
        x = 500 – 4236
        x = -3736
    d) 1235 + x = 6359
        x = 6359 – 1235
        x = 5124
    e) 15/2 . x = 5/9
        x = 5/9 : 15/2
        x = 5/9 . 2/15
        x = 10/135
        x = 2/27
