  1. Giải đáp:a) x –32 = 48
     ????=48+32
    ????=80
     Giải đáp   ????=80   b)5.(x-3) = 45   ????=60:5   Giải đáp????=12      c) 45 –(x + 9):2 = 6   ????=69

  2. a)x-32=48
    =>x=48+32=80
    =>x=80
    Vậy x=80
    b)5.(x-3)=45
    =>x-3=45:5=9
    =>x-3=9
    =>x=9+3=12
    =>x=12
    Vậy x=12
    c)45-(x+9):2=6
    =>(x+9):2=45-6=39
    =>(x+9):2=39
    =>x+9=39.2=78
    =>x+9=78
    =>x=78-9=69
    =>x=69
    Vậy x=69
