  1. Giải đáp:
     282-3 . (X-1)=141
    3.(X-1)        =282-141
    3.(X-1)        =141
    X-1             =141:3
     X-1           =47
    X              =47+1
    X               =48

  2. 282 – 3 . (x-1) = 141
    3 . (x-1) = 282 – 141
    3 . (x-1) = 141
    x – 1 = 141 : 3
    x – 1 = 47
    x = 47 + 1
    x = 48
    Vậy x = 48
