  1. a) x × 5 – 1295 = 1700
       x × 5         =1700 + 1295
        x × 5        =  2995
        x              =  2995 : 5
        x               = 599
    b) x : 9 = 2063 -1163
        x : 9  = 900
        x       = 900 × 9
        x        =   8100
    Xin hay nhất nhé 🙂
     

  2. a) $x$ × 5 – 1295 = 1700
        $x$ × 5            = 1700 + 1295
        $x$ × 5            = 2995
        $x$                   = 2995 : 5
        $x$                   = 599.
    b) $x$ : 9 = 2036 – 1163
        $x$ : 9 = 873
        $x$      = 873 × 9
        $x$      = 7857.
