  1. a) x+147584=266508
    =>x=266508-147584
    =>x=118924 
    Vậy x=118924 
    b) x-264781=48443+76442
    =>x-264781=124885
    =>x=124885+264781
    =>x=389666
    Vậy x=389666

    a) x + 147 584 = 266 508 
                         x  = 266 508 – 147 584
                         x  = 118 924
    b) x  – 264 781 = 48 443 + 76 442
        x  – 264 781 = 124 885
                         x  = 124 885 + 264 781
                         x  = 389 666
